Neurocog D/o Flashcards
Major Cognitive Disorder
New name for dementia
Psychological behavioral symptoms as well as acquired deficits in ADLs and IADLs
DSM neuro cognitive disorders
Delirium
MCI
Major Neurocognitive Disorder
Mild Cognitive Impairment
Memory/thinking problems, able to take care of self, no personality changes
-lose things, forgetting events/appointments, having trouble coming up with words, movement difficulties, problem with sense of smell
May be early sign of more serious memory problems
See MD every 6-12 mo for monitoring
Signs of Major Neurocognitive Disorder
Forgetfulness maybe normal
Sign if aging, but dementia is not
Sx: memory loss, loss of cognitive function, thinking, remembering, learning, reasoning, behavioral abilities- language skills, visual perception, attention, personality changes
Dementia types
Alzheimer’s Disease, Lewy Body dementia, frontotemporal dementia, vascular dementis
Factors that may cause memory problems
Head trauma/concussion
Blood clots
Tumors
Infections
Thyroid, kidney, or liver problems
Medication side effects
Mental health conditions ie depression
Alcohol/drug use
Sleep problems
Decreased B12
Decreased eating healthy foods
Causes of neuro-cognitive disorders
Brain injury by trauma: ICH, SAH, blood clot, concussion, hypoxia, hypercapnia, dementia due to stroke, Alzheimer’s d/s, creutzfeldt-Jakob Disorder, diffused lewy body disease, Huntington’s disease, MS, Normal pressure hydrocephalus, Parkinson’s disease, Pick’s disease
Metabolic cause: kidney disease, liver disease, thyroid disease, deficits in vitamin B1, B12 folate
Drug/alcohol withdrawal: wernicke-korsakoff
Infections: septicemia, encephalitis, syphilis, prion infection
Creutz-feldt Jakob Disease
Brain damage leading to rapid decline in movement (involuntary muscle movement) loss of mentation (thinking, reasoning, confusion) secondary to prions (eating infected meat), progress unusually fast, folded proteins destroys brain cells
Huntington’s Disease
Genetic defect on chromosome 4, CAG repeat
Sx: hallucinations, irritability, moodiness, restfulness/fidgeting, behavioral disturbances, paranoia, psychosis
Abnormal facial movements/grimacing, head turning to shift eye position, quick jerky movements of arms, legs, face, slow uncontrollable movements, unsteady gait, prancing and wide walk
Dementia
Multiple sclerosis
Autoimmune disease affecting brain and spinal cord, effects women more, inflammation and damage to myelin sheath
Sx: LOB, muscle spasms, numbness, trouble moving UE/LE, trouble walking, bowel/bladder problems, constipation, double vision, trouble urinating, tremors, tingling/burning, fatigue
Parkinson’s disease
Certain brain cells dying, shaking tremors, trouble walking, decreased dopamine, dx after 50, more in men
Sx: rigidity/stiffness, muscle aches/pains, constipation, slow blinking, drooling, no facial expressions, LBP when you stand, stooped posture, sweating, difficulty swallowing, slowed quiet speech, decreased handwriting
Pick’s Disease/frontotemporal dementia
Group of d/o due to damage in frontal and temporal lobes, genetic component, abnormal substances inside nerve cells in damaged areas, may be as young as 20, common 40-60, average 54
Seen in ALS, progressive supranuclear palsy
Behavior variant vs primary progressive aphasia
Not able to keep a job, compulsive, impulsive, inappropriate behavior, inability to function, interact socially, problems with personal hygiene, repetitive behavior, withdrawal, abrupt mood changes, decreased recognization of behavioral changes, decreased empathy, mutism, shrinking vocabulary, weak uncoordinated speech, echolalia, aphasia, increased tone, memory loss, apraxia, urinary incontinence
Extreme behavioral changes and lack of insight
Neuro degenerative disorders
Range of conditions that share primary feature of degeneration and loss if neurons in the brain, incurable/debilitating resulting in death of nerve cells, caused problems with movement (ataxia) and mental functions (dementia)
Most common: PD, Alzheimer’s disease
Less common: MS, atypical Parkinson’s, huntington disease, ALS
6 neurocognitive domains
1) perceptual-motor function: visual perception, visuo constructional reasoning, perceptual motor coordination
2) language: object naming, word finding, fluency, grammar/syntax, receptive language
3) learning/memory: free recall, cued recall, recognition, memory, semantic/autobiographical long term memory implicit learning
4) social cognition: theory of mind, insight, recognition of emotion
5) complex attention: sustained attention, divided attention, selective attention, processing speed
6) executive function: planning, decision-making, working memory, responding to feedback, inhibition, flexibility
Occipital lobe
Visual perceptual and visual
Motor, distance/depth perception, color determination, object/face recognition, memory function
Temporal lobe
Learning/memory, managing emotions, processing information, information from senses, storing/retrieving memories, understanding language
Parietal lobe
Perceptual motor function, language, receiving/processing sensory input of touch, pressure, heat, cold, and pain
Perception of body awareness and spatial coordinate system (mental map)
Frontal lobe
Executive function, social cognition, complex attention, role in voluntary movement, expressive language, managing higher, level executive function
Plan, organize, initiate, self-monitor, control one’s responses to achieve a goal
Functional Cognition
Combines constructs of function/cognition in context of performing everyday activities/occupations
Performance Skills
Observable, goal-directed actions that result in a client’s quality of performing desired occupations, skills supported by context
Assessing Functional cognition
Assess functional cognition, not specific cognitive skills, identifying client’s capacity to perform essential tasks given the totality of their abilities, includes use of strategies, habits, and routines, context/environmental resources
Why assess functional cognition?
Evaluate how a person can participate in/perform ADLs/IADL tasks, identify barriers to function, provide recommendation about appropriate care environments and facilitate a successful dc plan to match functional abilities, provide education about most effective ways to support/communicate with pts, clinicians, family/caregivers
Research support to assess cognitive fxn for all geriatrics pt, early detection necessary for client-centered care, early intervention maximizes function, safety, and independence
Performance based assessments
Executive Functional Performance Test (EFPT)
Performance Assessment of self care skills (PASS)
Weekly Calendar Planning Activity
Multiple Errands Test
Actual reality Assessment
AMPS
COPM
Executive Function Performance Test
Elements of executive function impacting function, individual’s capacity for independent functioning amount of assistance for task completion
Performance Assessment of Self Care Skills
Client-centered, performance based observational tool, assesses ADL/IADLs to provide snapshot of person’s ability to live (I)
Multiple Errands Test
Performance based test, measure how executive performance deficit affect functioning in natural environments, multiple versions, 5 different settings
Actual Reality Assessment
Performance based assessment approach use of internet to perform real everyday life activities
MS
AMPS: Assessment of motor and process skills
observational assessment that allows for the simultaneous evaluation of motor and process skills and their effect on the ability of an individual to perform complex or instrumental and personal activities of daily living
Based on MOHO
Skill based assessments
Examine foundational cognitive skills and allow clinician to extrapolate how deficits in these skills affect overall cognition

Do not identify mild cognitive impairments, failing to identify subset of clients at risk for failed care transitions
Use skip pattern/gateway: use functional cog tool for individuals who pass CAM/BIMs
Dementia/major neurocognitive disorder
Syndrome resulting from a variety of disease processes which there is deterioration in cognitive function beyond expected from normal aging
55 million people, 7th cause of deaty
Risk factors for dementia
Age: strongest risk factor, doubles every 5 yeas after 65
Genetics: family hx
Poor health: increased BP, increased cholesterol, diabetes, smoking
Race/ethnicity: African Americans are 2x more likely to develop dementia, hispanics 1.5x more likely to develop dementia, possibly due to increased heart disease with lower accessibility to preventative medicine
TBI
SDOH and dementia
Education: lower levels of education and lower levels of cognitive reserve
Decreased access to health-prevention dx and tx, risk factors such as heart disease and DM
Loneliness/social isolation increased risk
Socio-economic: lower socio-economic linked to increased dementia and may correlate with other factors
