Behavioral Flashcards
What ages characterizes an infant?
0-18 months
Defining characteristics of an infant? (markers for development)
Their reflexes
Infant reflexes
- Rooting reflex - A newborn infant will turn its head toward anything that strokes its cheek or mouth, searching for the object by moving its head in steadily decreasing arcs until the object is found.
- Palmar Grasp reflex - grip any object put in palm
- Moro reflex - limbs extend when child is startled
- Babinksi reflex - dorsiflexion of toes when the sole of foot is stroked
Rooting reflex
The rooting reflex assists in the act of breastfeeding. A newborn infant will turn its head toward anything that strokes its cheek or mouth, searching for the object by moving its head in steadily decreasing arcs until the object is found.
Palmar Grasp reflex
When an object is placed in the infant’s hand and strokes their palm, the fingers will close and they will grasp it with a palmar grasp.
Appears as early as 16 weeks and persists until 5 or 6 months of age.
Moro reflex
The Moro reflex is an infantile reflex normally present in all infants/newborns up to 4 or 5 months of age as a response to a sudden loss of support, when the infant feels as if it is falling. It involves three distinct components:
- spreading out the arms (abduction)
- unspreading the arms (adduction)
- crying (usually)
In summary: limbs extend when child is startled
Babinski reflex
Dorsiflexion of toes when the sole of foot is stroked
Dissappears as early as 1 year, but can take 2 years to go away.
One of the first tasks facing an infant (most important social relationship in its life)
Attachment to the parent or the primary caregiver
Stranger anxiety
After a child formed a strong attachment to his mother, he typically begins to show anxiety when handled by anyone other than the mother.
Whereas the child at 5 months was tolerant of being picked up by a stranger, the same child at 9 months will not tolerate this familarity.
Object permanence
During the first months of life, objects and people that leave the child’s LOS cease to exist for him.
Toward the end of the first year, children begin to understand that such objects continue to exist even if out of view –> sometimes results in separation anxiety (realization that mother is still there, but can no longer see)
Normal autistic phase
Occurs in the first postnatal month when children are in a state of self-involvement and alck of interest in others that in older children, signifies psychopathology.
What is the major task of the first year of life?
To form an attachment to the mother or the primary caregiver
Toddler (age group)
18 months to 3 years
Terrible twos
a period in a child’s early social development (typically around the age of two years) that is associated with defiant or unruly behavior.
Social interaction of toddlers
Toddlers like to be in the company of other children but do NOT yet play with others in a cooperative fashion.
Rather, play at this age takes the form of parallel play, that is playing next to but not reciprocally with other children.
Parallel play
Toddlers (18 months to 3 years) like to be in the company of other children but do NOT yet play with others in a cooperative fashion.
Rather, play at this age takes the form of parallel play, that is playing next to but not reciprocally with other children.
Toddler - milestones
- Parallel play with other children
- Terrible twos (defiance/negativity, but an understanding of language)
- Bladder control (beginning of bladder control and will be completely by 3 years in a majority and 4-5years in some others)
- Autonomy
- gender identity (understand if male/female)
At what age do children begin to gain bladder control?
They start to gain this at the end of their toddler years ~2 years. Control will be complete by typically 3rd year or sometimes go as late as 4 or 5 years
Preschool child (age group)
3-6 years
Preschool - milestones
- sibling rivalry
- regression
- between 2-4 years, vocabulary increases dramatically
- active fantasy life (imaginary life), but also understands they are not real
- cooperative play at 4 years
- strong fear of bodily injury (not a good time for elective surgeries)
- curiosity about bodies – playing doctor
Sibling rivalry
The birth of a sibling often occurs around age of 3 years in US, threatens the important primary relationship and may lead to jealousy or sibling rivalry
Regression
A consequence of sibling rivlary or any other life stressor such as changing residence.
The child may demand to have his bottle back or begin to wet the bed again etc… This reaction is temporary
Anxiety physical manifestations
Sympathetic NS - diaphoresis, mydriasis, tachycardia, tremor
GI/GU - diarrhea, increased urinary frequency
hyperventilation –> dizziness and syncope, parasthesia
Numbness and tingling in the extremiities and around the mouth
Anxiety psychological manifestations
restlessness, irritability, trouble concentrating, worry
Diagnosis of Anxiety (3)
- Be persistent (generally >6 months)
- shorter periods for children
- Interfere with normal functioning (work, job, marriage, etc…)
- Cause significant stress
Generalized Anxiety Disorder (GAD) - DSM-V
- Excessive anxiety/worry, occurring more days than nor for ≥ 6 months,
- Difficult to control worry
- associated with ≥ 3 of the following symptoms
- restlessness
- easily fatigued
- difficulty concentration
- irritability
- muscle tension
- sleep disturbance
- causes significant impairment
- No other explanation for symptoms (physical, chemical, or mental)
Cognitive behavioral therapy (CBT)
The front line treatment for a lot of anxiety disorders. Most evidence based mode of treatment
Use of congitive (thinking) and mental techniques as a mode of therapy to basically essentially remove the mind from a current state. Examples:
- statistical mental analysis
- guided imagery
Behavioral techniques
- deep breathing
- mediatation
- self-hypnosis
Cognitive behavioral therapy (CBT) - examples
Cognitive
- statistical mental analysis
- guided imagery
Behavioral techniques
- deep breathing
- mediatation
- self-hypnosis
Generalized Anxiety Disorder (GAD) - front line treatment medication
SSRIs and some SNRIs
Increases in SR or NE or both downregulates or desensitizes receptors
SSRI - Citalopram/Paroxetine
SNRI - venlafaxine / Duloxetine
SSRI/SNRI mechanism of treatment for GAD
Increases 5HT and NE or both which downregulates/desensitizes receptors
Put so much 5HT/NE into the patient’s system that when they do have an anxiety attack, their brain doesn’t really see it as much due to the desensitization
Medications for GAD
- Antidepressants - SSRIs/SNRIs front line treatment
- SSRI - esCitalopram, Paroxetine
- SNRIs - Venlafaxine, Duloxetine
- Increases 5HT/NE to downregulate/desensitize receptors
- Weight gain and sexual side effects
- Buspirone (5HT1a receptor agonist)
- initially lowers 5HT activity as these auto receptors (5HT1a are autoreceptors that downregulate 5HT activity). However overtime, the stimulate of these receptors causes their degradation and ultimately increase 5HT output.
- less sexual and weight gain side effects than SSRI/SNRIs
- ONLY FDA approved for GAD, nothing else
- initially lowers 5HT activity as these auto receptors (5HT1a are autoreceptors that downregulate 5HT activity). However overtime, the stimulate of these receptors causes their degradation and ultimately increase 5HT output.
- Benzodiazepines (GABA-A receptor modulator – allows more Cl- channels to open)
- 2nd line due to risk of addiction, falls, apnea
What drug is ONLY FDA approved for generalized anxiety disorder (GAD)?
- Buspirone (5HT1a receptor agonist)
-
Mechanism: initially lowers 5HT activity as these auto receptors (5HT1a are autoreceptors that downregulate 5HT activity). However overtime, the stimulate of these receptors causes their degradation and ultimately increase 5HT output.
- less sexual and weight gain side effects than SSRI/SNRIs
How are ß-blockers used for anxiety?
Only performance anxiety. Not used to treat generalized anxiety

- Recurrent panic attacks
- ≥ 1 attack followed by ≥ 1 month of ≥ 1 of the following
- concern about additional panic attacks or consequences
- significant maladaptive change in behavior related to attacks (typically phobic avoidance –agoraphobia)
- No other explanations for symptoms (physical, chemical, mental)

Panic disorder occurence/prevalence
1.5-3.5% prevalencein general population
Females > males
Panic disorder treatment
Therapy
- Cognitive behavioral therapy
- Systemic desensitization(step by step progression to doing the thing you fear the most) or flooding (immerse the person in the environment they fear the most and basically overflood their senses and eventually fine)
- Psychodynamic therapy
Medication
- emergency treatment: fast-acting benzodiazepines (alprazolam)
- Long term 1st line: SSRI/SNRI
- Intermediate or long acting benzos (not 1st line. 2nd due to addiction potential)
Combination treatment
Systemic desensitization or flooding
- Systemic desensitization - step by step progression to doing the thing you fear the most
- Flooding - immersion of the person in the environment they fear the most and basically overflood their senses and eventually fine
A type of cognitive behavioral treatment. (used in panic disorders, although not common)
Performance anxiety
A type of social anxiety. Technically called “social anxiety - performance type”
ONLY associated with performances and the anxiety that develops in any relationship to performances.
fear is restricted to public speaking or performing and does not generalize to other social aspects of life

- marked fear/anxiety about a specific object/situation
- object/situation almost always provokes fear/anxiety
- actively avoids object/situation
- fear/anxiety out of proportion to actual danger

Obsessive Compulsive Disorder (OCD) – DSM-V Definition
Criterion A: The presence of obsessions and compulsions
Criterion B: These obsessions and compulsions must be either
- Time consuming (>1hr/day) or
- Cause clinically significant distress
{Either 1 or 2 from Criterion B}
- Are not substance-induced
- Not better explained as symptoms of another mental or medical disorder
What is an ‘obsession’?
Recurrent/persistent thoughts, urges, and/or images
Intrusive & unwanted
- sometimes called ego dystonic (means person recognizes it is wrong and doesn’t want to do it)
- cause the person anxiety/distress
Patient treis to ignore/supress these intrusive thoughts OR they try to neutralize them with a thought or action
- this is an undoing ego defense mechanism
- a compulsion to do something to reduce the anxiety/distress
What is an ‘compulsion’?
Repetitive behavior or activity that the patient performs in response to an obsession or as a set of rules that must be strictly adhered to.
- A compulsion typically undoes or reduces anxiety (typically an obession)
- stopping the compulsion often dramatically increases anxiety
ego-dystonic
of or relating to aspects of one’s behavior or attitudes viewed as inconsistent with one’s fundamental beliefs and personality (contrasted with ego-syntonic )
Ego-syntonic
a term referring to behaviors, values, and feelings that are in harmony with or acceptable to the needs and goals of the ego, or consistent with one’s ideal self-image.
OCD prevalence
Men & women equally affected
Lifetime prevalence: 2-3%
50-70% have onset after a stressful event
Mean onset: Men = 19 years / Women = 22 years
OCD prognosis
Long, but variable course
20-30% have significant improvement
40-50% have moderate improvement
20-40% remain ill or worsen
Likely the hardest anxiety to treat
OCD - treatment
Psychotherapy
- CBT: as effective as pharmacotherapy, with longer-lasting effecting
- Exposure and response prevention (ERP) - basically step by step controlled exposure to withhold the compulsion, a desensitization protocol
- ACT: Acceptance and commitment Therapy for obsessions - putting the image in their head of their compulsion. So a controlled method of basically desensitization to the obsession.
- Supportive Psychotherapy? Dynamic Psychotherapy
Pharmacotherapy (best results when + psychotherapy)
- 1st line: SSRIs, higher-dosage and duration than MDD (major depressive disorder)
- 2nd line: clomipramine (a TCA, approved for OCD)
- 3rd line: antipsychotics, other antidepressants
- Benzodiapeine sedatives do not work.
Exposure and response prevention (ERP)
a step by step controlled exposure to withhold the compulsion, a desensitization protocol. Used in the treatment for OCD
ACT: Acceptance and commitment Therapy
putting the image in their head of their obsession. If it is fear of the death of her family, keep talking to her about the death of her family and conjure images of it in her head until the point that the idea is desensitized.
Basically desensitization to the point where the patient no longer cares or just accepts it for what it is and does not have any more compulsions for that obsession
Used in treatment for OCD
First drug approved for OCD
Clomipramine - a tricyclic antidepressant (TCA) - selective serotonin reuptake inhibitor (200x stronger affinity than for NE)
Also has antagonistic properties at the histamine H1 receptor, muscarinic ACh receptors and α1 adrenergic receptor
- difference between SSRIs and TCAs is the anti-cholinergic properties –> dry mouth, blurred vision, tachycardia, constipation
- very hard for patients to stay on these drugs due to side effects
What is most common thing that could cause PTSD?
Death of a loved one
What is the most likely thing to caused PTSD?
Assault

Acute Stress Disorder (ASD)
Basically early PTSD
Key is the timeframe. PTSD
Only difference: Criteria B-D must persist for 3days - 1 month after exposure (vs >1 month for PTSD)
Earlier treatment can decrease the risk of full PTSD onset
PTSD & ASD - summary/short version

Foli imposee - likely has the delusion
Folie simultanee - incorporates delusion into his/her life
Cotard’s delusion
a rare mental illness, in which an afflicted person holds the delusion that they are dead, either figuratively or literally.
Typically occurs with another disease, but can occur by itself.

delusional parasitosis
aka morgellons
patient believes they are infested, can see and often see or feel parasites in or on them
Erotomania
type of delusion in which the affected person believes that another person, usually a stranger, high-status or famous person, is in love with him or her
Ilness often occurs during psychosis, especially in patients with schizophrenia, delusional disorder or bipolar mania
treatment
- these are psychotic conditions w/ the assumption that there is too much mesolimbic dopamine activity similar to schizophrenia
- antipsychotics are sometimes effective, but often times not
- psychotherapy may help patients cope, lower anxiety or agitation
- be non-judgemental, nonincredulous, nonchallenging, empathic, facilitate communication

Why do antihistamines cause weight gain?
Anything that blocks H1 receptors blocks the satiety center in the brain causing one to continue eating as if they are never full
What drugs are associated with weight gain?
block H1 – blocks satiety center
anti-muscarinics (ACh)
block 5HT2c – causes fat cells to grow bigger
block D2 receptor – increases in prolactin is associated with weight gain
Weight loss management drugs
- Amphetamines - decreases appetite
- Orlistat - lipase inhibitor
- Topiramate/Phentermine combo - improved carb metabolism, less gluconeogenesis, appetite suppressant
- Naltrexone/bupropion combo - dampens reward of eating, appetite suppressant
- Lorcaserin - blocks 5H2C receptors to increase metabolism, lessen tendency to store fat, improve leptin sensitivity?
Amphetamines - weight loss mechanism
decreases appetite
Orlistat
lipase inhibitor (fat inhibitor)
Coats your gut and essentially prevents the absorption of fat. You poop it out. Feces very oily and will definitely feel accidents when eating high fat diets
Topiramate/Phentermine combo
Epilepsy medicine
improved carb metabolism, less gluconeogenesis, appetite suppressant
Naltrexone/bupropion combo
Naltrexone - NE reuptake inhibitor. NE goes up –> curves appetite
Dampens reward of eating, appetite suppressant
Lorcaserin
stimulate 5H2C receptors to increase metabolism, lessen tendency to store fat, improve leptin sensitivity?
Anorexia Nervosa - diagnosis
DSM-V
- Restriction of energy intake requirements –> low body weight
- fear of gaining weight
- body image disturbance (dysmorphism)
DSM-IV: includes the above 3 and:
- refusal to maintain 85% typical weight
- Missed menstrual cycles x3 (removed as it does not apply to men)
Severity is based off BMI
Personality profile of aneroxics
More rigid, controlling and inflexible
high achieving (type A personalities)
obsessive compulsive
perfectionists

- loss of control
- compensatory behaviors necessary for diagnosis. behaviors such as vomiting, laxative use, enemas, diuretics, exercise
- binges 1X/wk for 3 months
bulimia diagnosis
- purging vs non-purging types w/ no anorexia present
- compensatory behaviors necessary for diagnosis, such as vomiting, laxative use, enemas, diuretics, exercise
- binges 1X/wk for 3 months
bulimia - personality profile
erratic
emotional
chaotic
outgoing, angry, impulsive traits
bulimia - cause
believe to be low serotonin
bulimia - medical issues
- poor dentition, enamel loss, cavities – typically associated with excess vomiting
- abraided knuckles (Russell’s Sign) - from the afflicted’s knuckles making contact with the incisor teeth during the act of inducing the gag reflex at the back of the throat with their finger(s).
- Normal/overweight
- sexually active
- lab changes
- low PO4, low Mg
- high amylase
- salivary enlargement
- esophagitis/tears
Russell’s Sign - associated with bulimia
defined as calluses on the knuckles or back of the hand due to repeated self-induced vomiting over long periods of time (ie abraided knuckles)
The condition generally arises from the afflicted’s knuckles making contact with the incisor teeth during the act of inducing the gag reflex at the back of the throat with their finger(s).

bulimia - treatment medications
SSRIs are approved
PICA
persistent eating of nonutritive substances x 1 months
not developmentally or culturally appropriate
not medical or from intellectual disability or autism
Rumination
repeated regurgitation and re-chewing of food
no weight gain
not medical or from intellectual disability or autism
often before 6 years
Avoidant/restrictive food intake disorder
- Failure to meet diet/energy needs
- weight loss, nutritional deficiency, supplementation needed, psychosocial distress
essentially doesn’t meet full anorexia criteria
Binge eating disorder
- Binges
- do NOT need the compensatory behavior
- Lack of congrol
- ego dystonic
- 1x/wk for 3 months
- No purges or compensations
- Newest FDA approved treatment is stimulate called lisdexafetamine (a prodrug in the amphetamine class)
basically a milder version of bulimia
milder version of anorexia
avoidant/restriction food intake disorder
milder form of bulimia and why?
binge eating disorder
only difference is there isn’t a requirement for the compensatory behavior
Age associated cognitive changes
- difficulty retrieving words and names
- slower processing speed
- difficulty sustaining attention when faced with competing environmental stimuli
- learning something new takes a bigger effort
- no functional impairment
Mild cognitive impairment (MCI)
basically people who have some problems with memory but are otherwise functioning perfectly normally.
- NO loss of functional capacity (this is how you distinguish from AD or other types)
Not demented.
Amnestic MCI (mild cognitive impairment)
Memory loss not meeting the criteria for dementia
Progresses to AD (alzheimer disease) at rate of 10-15% vs 1-3% incidence in general population
may be the earliest phase of AD
Genes associated with early-onset AD
X #1 - abnormal presenilin 2
X #14 - abnormal presenilin 1
X #21 - abnormal amyloid precursor protein
Genes associated with late-onset AD
Chromosome 19 - apolipoprotein E4 gene implicated
late-onset AD
most common form
develops after age 60
combination of factors likely responsible
Chromosome 19 - apolipoprotein E4 gene implicated
most common cause of dementia
alzheimer disease
Cerebral atrophy associated with Alzheimer Disease
atrophy will occur in the frontal, temporal and parietal lobes.
occipital lobe spared for unknown reason.
What makes Alzheimer disease unique?
ONLY disease that is both a beta amyloidopathy and a tauopathy
- extracellular deposits of beta-amyloid peptide (Aß) associated with dystrophic neurites
- Filamentous intracellular inclusions of tau proteins called neurofibrillary tangles (NFTs) and neuropil threats (NTs)
Most atrophied part of brain in Alzheimer
Atrophy in parietal, temporal and frontal lobes with occipital lobe sparring.
Atrophy of the hippocampus most pronounced over any other part.
How do neurofilament tangles arise and why are they dangerous? (tau)
NFTs arise due to hyperphosphoyrlation of tau, a microtubule-associated protein.
They are dangerous because they conform the neuron structure and are insoluble. When the neuron dies due to aggregation of the tau protein, the body cannot clear it (insoluble)
Alzheimer Disease

Depression vs dementia
Depression in old people can often lead to AD.
The symptoms of depression and dementia often overlap
- Patients with primary depression
- demonstrate less motivation during cognitive testing
- express cognitive complaints that exceed measured deficits
- maintain language and motor skills
- People with dementia on the other hand will:
- try very hard to do well
- positive review of systems
Frontotemporal Dementia
Also known as Pick’s Disease
Characterized by emotional blunting resulting in decline in social interpersonal conduct –> worldwind of inappropriateness.
- Insidious onset, gradual progression
- early impairment in regulation of personal conduct with loss of insight
- early decline in social interpersonal conduct
- early emotional blunting
- characterized by behavioral abnormalities
- memory loss and dementia occurs later
Pick’s Disease
Also known as frontotemporal dementia
Characterized by emotional blunting resulting in decline in social interpersonal conduct –> worldwind of inappropriateness.
- Insidious onset, gradual progression
- early impairment in regulation of personal conduct with loss of insight
- early decline in social interpersonal conduct
- early emotional blunting
- characterized by behavioral abnormalities
- memory loss and dementia occurs later
Frontotemporal dementia - treatment
No role for cholinesterase inhibitors
Careful use of atypical antipsychotics (quetiapine, risperdol etc..)
Divalproex for behavior control
SSRIs for irritability, depression, impulsive behaviors.
Congo red
stains amyloid fibrils (assoicated with Alzheimer Disease)
Alzheimer disease - treatment categories
Cholinergic therapy (rivastigmine, donepezil, galantamine)
NMDA receptor antagonists (memantine)
Investigational agents
Treatment of neuropsychiatric symptoms in AD patients
Why do anticholinesterase’s work? (for AD)
There is a degeneration of the basal nucleus of Meynert (aka nucleus basalis) in AD that is normally responsible for ACh production –> ACh deficiency.
This contributes to memory deficits that characterize this disorder
Side effect of AChE inhibitors
Typically associated with GI –> N&V
Sleep disturbance also associated
Donepezil
Mech: inhibits AChE
Metabolims: Cyt P450
Therapeutics: all stages of Alzheimer Disease (only drug approved for all stages)
SE: N&V, sleep disturbance
Rivastigmine
Mech: Inhibits AChE and BuChE
Metabolism: hydrolysis by cholinesterases
Therapeutics: only drug in transdermal-patch form. Used in treatment for AD.
SE: N&V, sleep disturbance
Galantamine
Mech: inhibits AChE and allosteric modulator of nicotinic receptors
Metabolism: Cyp450
Therapeutics: Alzheimer disease. Not used as commonly as donepezil and rivastgimine
SE: N&V, sleep disturbance
Memantine - what does it do and why does it work?
Mechanism: NMDA receptor antagonist
SE: dizziness, confusion, headache, constipation
Metabolism: mostly excreted unchanged in urine
Therapeutics: Alzheimer disease
- in AD, there is abnormal (increased) NMDAR activity. Excessive activity –> excitotoxicity –> neuronal damage/death
- This drug aims to reduce that excessive activity. Side effects are associated with downregulation activity
Lewy bodies
fibriller deposits of a presynaptic terminal protein call α-synuclein (Lewy body)
Most commonly found in
- Parkinson’s Disease
- Dementia with Lewy Bodies
Oversimplification:
- if disease happened first in cortex –> dementia w/ lewy bodies
- if disease happened first in substantia nigra –> Parkinson
Parkinson Disease
1-2% of people over 65
Most cases sporadic
Cardinal symptoms
- resting tremor
- difficulty initiating movement (akinesia)
- slowed movement (bradykinesia)
- rigidity
- shuffling gait
- postural instability
- dementia occurs in some cases
Dopaminergic deficit
Response to L-Dopa therapy
Parkinson Disease - cardinal symptoms

What is required histologically to diagnose Parkingson Disease?
Lewy bodies in substantia nigra
What is the disease diagnosis if, histologically, there are lewy bodies in substantia nigra?
Parkingson disease
What is the disease diagnosis if the following is found on histology?
- Pallor of the substantia nigra
- No presence of lewy bodies
Progressive supranuclear palsy or
Cortical basilar degeneration
MUST have Lewy bodies to diagnose Parkinson
Neuropathology of Parkinson Disease
Gross: pallor of the substantia nigra
Microscopic:
- degeneration and loss of the pigmented, dopaminergic neurons of the substantia nigra pars compacta and other pigmented neurosn of the brainstem such as locus ceruleus
- Neurons contain eosinophilic inclusions called Lewy Bodies
- Other nuceli such as the cholinergic nucleus basalis of Meynert are also affected
- Striatum, thalamus and other cortical regions are functionally affected due to the loss of dopaminergic input
Dementia with Lewy Bodies (DLB)
Sporadic, primarily late-onset
Memory frequently less affected compared to AD
Frontal and subcortical features – deficits in attention and alertness are prominent
pronounced fluctuations and variations in symptoms
Neuropsychiatric symptoms – vivid visual hallucinations, delusions
Motors symptoms of PD are variably present
Neuropathology of (DLB)
Gross: Nigral pallor. Cortical atrophy is less severe than in AD. Atrophy of limbic areas is often significant.
Microscopic:
1) “Cortical”-type Lewy bodies (LBs) in frontal, temporal, and insular cortex, and in limbic areas (amygdala, cingulate gyrus – the first places where LBs form in this disease).
2) Nigral LBs.
3) LNs (lewy neurites), especially in hippocampus and striatum.
4) DLB patients usually have plaques and tangles, and a dual diagnosis of DLB and AD applies in most cases.
First place that Lewy bodies form in Dementia w/ Lewy Bodies
amygdala, and cingulate gyrus
Does the brain atrophy in DLB like it does with AD?
No. Barely any cortical atrophy. Biggest prominence is the pallor that develops in the substantia nigra.
Lewy Body Dementia - clinical features
Short term memory loss, gradual onset
Visual hallucinations - more so than any of the other diseases
Cognitive fluctuations
REM sleep disorder is common - will pantomime (act out) their dreams
Frequent falls
Autonomic dysfunction
Lewy Body - treatment
- Cholinesterase inhibitors may provide symptomatic support
- Trial of carbidopa/levodopa for severe movement symptoms
- AVOID antipsychotic drugs due to increased sensitivity
- enhance any Parkinson symptoms
- REM Sleep Disorder: Clonazepam
Lewy Body vs. Parkinson’s Dementia
Lewy Body Dementia
- Onset of dementia within 12 months of parkinsonism
Parkinson’s disease and dementia
- Onset of dementia more than 12 months after the diagnosis of PD

Id - structural model of the mind
This refers to the “child” within someone or the childish characteristics
structural model of the mind (Id, Ego, Superego)
Id = child
Ego = adult (growing, evolving and has to do with “I”)
Superego = parent (rules, morales, values – develops based on input from authorities)

Occurs when ego is under stress.
“can’t deal with this” –> anxiety –> ego defense mechanisms

Transference
Patient’s unconscious “transfer” and replay of relationship with influential figures from the past. More likely w/ physicians.
Positive: unrealistic expectations
Negative: Mistrust, missed appointments, non-adherence, poor outcomes
Countertransference
The MD’s transference to the patient - positive or negative.
Acute vs chronic pain
Acute - 1 week or less
chronic - considered an autonmous disease. present for at least 6 months
Inflammatory vs neuropathic pain
Inflammatory - typically refers to acute pain caused by the onset of trauma or inflammation which causes the release of prostaglandins that can mediate pain. Can be reduced with NSAIDs
Neuropathic pain - refers to chronic pain typically caused by miscellaneous nerve firings (or memory of pain potentiated via glutamate activation of NMDA receptors).
Opiates vis Opioids
Opiates - derivates fo poppy plant: heroin, morphine
Opioids - any drugs that occupies opioid receptors: fentanyl, methadone
NSAIDs - mechanism
Inhibit COX - enzyme that converts arachidonic acid to prostaglandins and thromboxane which provoke tissue inflammation
NSAIDs - side effects
Prostaglandins protect the stomach lining from acid. COX-2 specific inhibitors; celecoxib and low dose meloxicam (7.5 mg/day) cause less gastric irritation
Fever is mediated by what compound (associated with NSAIDs)
Fever is caused by prostaglandin E2. PGE2 signals hypothalamus to increase body’s thermal set point
endorphin
endogenous morphine
Treatment for neuropathic pain
anticovulsants
tricyclics
Opioids doesn’t really tone down the pain, but rather makes the patient less concernd about the pain
Treatment for inflammatory pain
NSAIDs
Epilepsy
Epilepsy is a condition where cortical neurons kindle and then fire in synchrony causing a neuromuscular seizure to occur.
All antiepileptic drugs (AEDs) function by lowering a neuron’s ability to fire by hyperpolarization
Antiepileptics drugs - mechanism
All antiepileptic drugs (AEDs) function by lowering a neuron’s ability to fire by hyperpolarization.
They primarily dampen sodium and potassium influx. There are drugs targeted for chloride influx and also glutamate.
