persistent or recurrent feelings of detachment from one’s self, environment, or social situation. reality testing remans intact during episode. treat with anti anxiety agents or SSRIs.
25
how to treat impulse control disorder
SSRI. low levels of serotonin have been associated with impulsiveness and aggression. anticonvulsants, lithium, propranolol. individual psychotherapy is difficult and/or family therapy may be useful
26
what is often comorbid with bulimia
kleptomania. 1/4 of BN patients
27
treatment for trichitolomania
SSRI, lithium, antipsychotics. hypnosis, relaxation techniques. behavioral therapy- substitites anoher habit
28
hypchondriasis vs factitious
hypo: anxiety is main thing- it doesnt really go away. they wouldn't want aggressive stuff.
29
pathophys of ADHD
dopamine filters the noise. norepinephrine increases the volume.
30
when do you use clonidine
BP and ADHD and opiate withdrawal
31
what med to give if depressed w/heart disease
sertraline (or citalopram)
32
can you try ECT after MI?
after 2 months- yes. after 2 good trials, try it.
33
angelman syndrome sxs
chromosome 15-developmental delay, movement or balance disorder, happy demeanor, sometimes seizures, short
34
prader-willi syndrome sxs
chromosome 15- cog diabilities, low muscle tone, short stature, chronic feeling of hunger-> obesity, almond shaped eyes
35
signs of porphyra
depression. GI pain, romberg sign, decreased joint position sense
36
carbidopa vs levidopa
levodopa crosses the BBB, carbidopa does not. carbidopa presents conversion of levodopa in the periphery. Once levodopa crosses BBB, it is free to be converted to dopamine. levodopa can cause depression or mania.
37
pathology and pathophysio of parkinsons
loss of cells in the substantial nigra of the basal ganglia-> decrease in dopamine and loss of dopaminergic tracts
38
53 yr old woman with changes in personality over last 6 years. personality became irritable, sexually uninhibited, and loud. intermittent jerky movements. MRI will likely reveal..
caudate atrophy. this is huntingtons
39
Huntingtons. onset? path? diagnostic? MRI? treatment?
35-50.
trinucleotide repeat on short arm of chromosome 4. primarily affects basal ganglia.
MRI shows caudate atrophy and sometimes cortical atrophy. genetic test and MRI are diagnostic.
no effective treatment
40
Huntingtons sxs vs FTD sxs
both have personality changes but Huntingtons has more movement- bizarre choreiform, muscle hypertonicity, and depression and psychosis are common.. FTD has more aphasia, apraxia, agnosia.
41
cortical dementia vs. subcortical dementia
cortial: alzheimer, Pick's, CJD: decline in intellectual functioning.
subcortical: huntingtons, parkinsons, NPH, multi-infarct dementia- more prominent affective and movement sxs
42
parent management therapy
aims to change parenting behaviors, positive reinforcement, used for disruptive behavior like ODD and Conduct Disorder
43
are related sleep changes in elderly.
sleep less at night and nap during the day. period of deep sleep (stage 4) becomes shorter and eventually disappears. they awaken more throughout the night. not a sleep disorder.
44
preferred treatment for narcolepsy
modanifil. amphetamine stimulant are second line because of their abuse potential.

49
how to qualify for primary hypersomnia
at least 1 month of daytime sleepiness or excessive sleep not attributable to medical conditions, medications, poor sleep hygiene, insufficient sleep or narcolepsy. usually begins in adolescence.
50
treatment for primary hypersomnia
stimulant are first line. sometimes SSRI may help
51
EDS vs fatigue
EDS: falling asleep when you don't want to (common with OSA). fatigue is being too tired to complete activities
52
obstructive sleep apnea versus central sleep apnea? treatment?
OSA: respiratory effort is present but ventilation is obstructed by physical obstruction of airflow. tx: nCPAP (nasal continuous positive airway pressure), weight loss, uvulopalatoplasty
CSA: periodic cessation of respiratory effort. tx: bPAP with a backup rated (mechanical ventilation)
53
night terror disorder vs nightmare disorder
nightmare disorder: fully awaken and remember episode

pain disorder vs somatization disorder
somatization is before age 30. at least 2 GI, 1 repro, 1 neuro, 4 pain. pain is >6 mo pain unexplained by other stuff.
55
borderline vs histrionic
histrionic are more funcitonal. BPD are more likely to have depression and commit suicide.
56
narcissistic vs. OCPD
both want assertiveness and achievement but OCPD are motivated by the work itself, narcissistic by the status
57
what test to exclude reversible causes of dementia
15% of dementia is reversible. check VDRL (syphilis), electorlytes, TFT, CBC, b12/folate, brain CT or MRI
58
dementia+ loss of position sense + megaloblasts on CBC
vitamin B12 deficinecy
59
dementia + diminished position/vibration sense + Argyll Robertson pupils
neurosyphillis- check CSF VDRL or CSF FTA-ADS
60
2 types of delirium
quiet (depressed, failure to thrive) and agitated (pulling out lines, may hallucinate)
61
what should you do for delirium
fix reversible causes. give antipsychotic like seroquel. avoid napping. keep lights on shades open during the day. hold for sedation in orders
62
ddx for delirium
AEIOU TIPS. alcohol, electrolytes, iatrogenic, oxygen hypoxia, uremia/encephalopathy, trauma, infecion, poison, seizures (post ictal)

yes- for depression
72
vascular dementia vs. alzheimers
vascular- also get focal near sxs like hyperreflexia and prosthesis. greater preservation of personality in vascular dementia.
73
meds for parkinsosn
carbidopa/levodopa. amantidine (increases dopamine). anticholinergics (relieve tremor), bromocriptine (increase dopamine), MAO-B (e.g.: selegeline. inhibit breakdown of dopamine

a person gets dementia after going to woods. what do you think?
lyme disease
82
alzheimers F:M
3:1
83
structural changes in alzheimers
decrease in acetylcholine due to a loss of noradrenergic neurons in basal creels and decreased choline transferase (required for ACH)
84
when do you find senile plaques and neurofibrillary tangles
alzheimers, Down syndrome, normal aging (downs is at increased risk of getting alzhimers- increased 21)
85

89
in LBD, how fast after parkinsonian sxs do you need dementia
within 12 months. if >12 mo, it is parkinson disease dementia
90
tx for LBD
cholinesterase inhibitors help improve hallucinations. psychostimualnts, levodopa/carbidopa, ad dopamine agonists may improve cognition, apathy, and psychomotor slowing, atypical neuroleptics for agitations anddleusions, klonopin for REM sleep behavior d/o
91
which is more rapid to death: Pick or ALzheimers
Pick. mean duration of illness to death is 4-6 years
92
tx for pick

clonazapam for 90% of pts. also try imipramine, carbamazepine, parmipexole, levodopa
117
does the desire for sexual activity decease with age
no. men need more direct stimulation and more time to orgasm. intensity decreases and refractory period increases.
118
drugs and libido
alcohol and MJ enhance it by decreasing inhibition but then long term use decreases desire. narcotics inhibit it. cocaine and amphetamines increase it by stimulating dopamine receptors
119
