Random Pre-Test facts Flashcards
Kluver Bucy vs Temporal Lobe Epilepsy
TLE
- hyposexual
- intense fixation on ideas (viscosity)
- emotional INTENSITY
Kluver Bucy
- hypersexual
- hyperoral
- shifting attention (opposite of viscous)
- placidity
Episodic Memory Location
lasts seconds Med. temporal lob ant. thalamic nucleus mamillary body fornix prefrontal cortex
Semantic Memory
inferolateral temporal lobes
- will allow patients to answer questions like the color of a certain breed of dog or how orange and apple are different
Procedural memory
Basal ganglia
cerebellum
Supplementary motor area
working memory
ability to store memory for several seconds while rest of brain works on it
REM sleep EEG waves
sawtooth, low voltage, fast activity
Also see inc HR, blood pressure and penile/clitoral erection
Tactile Agnosia
cannot recognize objects based on touch
- caused by damage to border of somatosensory and association areas of post. parietal lobe
preserved functions in frontal lobe
memory, cognition, IQ, language, praxis
Prader Willi
underweight infant - over weight early child
other sx include ANS dysreg, muscle weakness, hypotonic, mild to moderate MR, temper tantrum, violent outburst, perseveration, skin picking, and a tendency to be argumentative, oppositional and rigid
Gerstman syndrome
- parietal lobe lesion - Agraphia Acalculia Right-left Disorientation Finger Angosia
Apperceptive Visual Agnosia
inability to ID and draw items using visual cues w/ preservation of other senses
Prosopagnosia
caused by damage to inf. temporal cortices from visual assoc. area of left parietal lobe
Balint Syndrome
Bilateral Occipital lobe lesions
optic ataxia, oculomotor apraxia and simultanagnosia
psych issues seen in Fragile X
anxiety, dysthymia, antisocial p/d, OCD and ADHD
Ritalin OD
mimics cocaine except ALSO has hyperthermia
PCP intoxication
nystagmus,, drooling, vomitting,
at High doses paranoid, delusions, disorg thinking and catatonia
Dysfxn of Orbitofrontal Area
Disinhibition, irritability, lability, euphoria, and lack of remorse
Impaired insight and judgment
Distractible
looks like Antisocial PD, intermittent explosive disorder, and episodic dyscontrol syndrome
Dysfxn of Dorsolateral area
Deficiency in planning, monitoring, flexibility, and motivation
Can’t see foresight and feedback
can’t maintain goal-directedness, focus or sustained effort
inattentive and undermotivated
linger on trivial thoughts
Caudate functions
only allows goal directed movements
without it you do random motions –> choreoform movements
Folic Acid Deficiency
dialysis, heavy smokers, pregnancy, celiac disease
Beta sleep waves
13+ Hz
symmetric on both sides and most active in frontal lobe
closely linked to motor behavior but is attenuated with motor behavior
Seen in Active/Busy/Anxious thinking
low amplitude, with multiple, varying frequencies,
seen in active concentration
look for Rhythmic beta w/ dominant set of frequencies assoc w/ various pathologies and drug effects –> BZD
Delta waves
highest amplitude, lowest wave length
normally seen in babies
seen focally in subcortical lesions
and in gen distribution w/ diffuse lesions, metabolic encephalopathy, or deep midline lesions
Theta waves
younger children, seen in medication that makes you drowsy
seen in creative states
