ch. 16 - disorganized thinking

schizophrenia psychomotor symptom

catatonia

neurobio of schiz

• young adulthood

• enlarged ventricles

• disorganized pyramidal

prolonged stress leads to overactive

HPA axis

ketamine is a glutamate…

antagonist (for depression)

ECT

seizures produce neurotropic factors that activate cells

• given w anesthetic + muscle relaxant

TMS

tissure depolarizing increases cell firing

brain mechanims of anxiety

overactive cingulate cortex+ parahippocampal + amygdala + pre-frontal cortex

crhonic traumatic encephelopathy

neurofibrillary tangles (tau) + plaques + enlarged ventricles

ischemic

blockage (need imediate)

hemorraghic

bleeding

FAST

• face

• arms

• speech

• time

effects of storke

• massive amounts of glutamate

• toxic Ca2+ levels

• brain inflammation

• neural shock (diaschis)

• changes in metabolism

stroke therapy

• clot busting drugs

• neuroprotectant

epilepsy

• abnormal EEG

• likely when asleep

focal seizure

• focal aware

• focal unaware (mem impair)

generalzied seizure

• normal EEg

• tonic phase

• clonic phase

• depression

statis epilepticus treatment

GABA agonist or glutamte antagonist

intractable epilepsy

when drugs dont help so need surgery

neurosurgical treatment of parkinsons

DBS on subthalamic nucleus to increase thalamus movement
