17
Q

ADHD criteria

A

at least 6 months of 6 or more specific symptoms of inattention or Hyperactivity

Sign symptoms present before age 12

Symptoms in 2 or more settings

18
Q

Transient Global amnesia

A

occurs in older men, only recent event and information can be remembered for a few minutes

Causes: TIA, basilar artery migraine, physical or psychic stress

19
Q

Wernicke-Korsakoff anmesia

A

seen in alcoholics due to thiamine(B1) deficiency

Confabulation(making up stories to fill in the gaps) and confusion are hallmarks of the amnesia

Diencephalic Amnesia

20
Q

Diencephalic Amnesias characteristics

A

Remote memory deficit
Normal Rate of Forgetting
Poor insight and confabulation

EX: Werinke-korsakoff

21
Q

Bilateral Mesial Temporal Amnesias

A

Intact remote memory
Rapid forgetting
Impaired Consolidation
Intact insight

22
Q

Hippocampal Trisynaptic Circuit Route

A

input to Entorhinal

  1. Dentate Gyrus to 2.CA3 pyramidal cells VIA mossy fibers
  2. CA3 pyramidal cells to
  3. CA1 pyramidal cells VIA Schaffer collateral

Ends at Subiculum and back to Entorninal to generate synaptic plasticity

23
Q

Extended Memory System

A

Perirhinal and parahippocampal region

24
Q

Delirium pathology

A

Deficit in cholinergic function

Deficit in Reticular Activating system

25
Q

Neuroanatomical cause Alzheimer’s

A

Cortical atrophy
Hippocampal atrophy
Enlarged ventricles

26
Q

A

Multiple neurotransmitter deficiencies

Loss of cholinergic ACH in the nucleus basalis of Meynert

27
Q

Vascular Dementia

A

Caused by multiple infarcts patient typically has history of CVD

  • Sudden
  • Heachaches and seizures

Treat CVD first

28
Q

Frontotemporal Dementia

A

AKA Picks

Similar to Alzheimer’s disease but “frontal signs prominent early”

*Disinhibition and Personality changes

29
Q

Lew Body Dementia

A

Fluctuating cognition
Visual hallucinations
mild parkinsonism
