ANSWERS

Question:
1. Alzheimer's Disase Facts
Answer:
50-70% of all dementias, affects women 2:1, unknown cause neurofibulary tangules, neurotic plaques, and
granulovacuolar degeneration

Question:
2. Early Alzheimer's Symptoms
Answer:
difficult word retreival occasional paraphasias subtle comprehension problems memory and orientation
challenges are first symptoms

Question:
3. Middle Alzheimer's Symptoms
Answer:
comprehension impairment more obvious word retrieval, sentence fragments, passive px (prognosis) topic
maintenance conversations more difficult

Question:
4. Late Alzheimer's Symptoms
Answer:
severely compromised reading/writing non-functional, bizarre, devoid of meaning unaware of errors
echolalic

Question:
5. Diseases of the Basal Ganglia
Answer:
Parkinson's (dopamine) Huntington's (brain shrinks) Wilson's Athetosis lesions of BG cause a loss of
inhibitory control over motor movements

Question:
6. Frontal Association Area
Answer:
most anterior region of the brain; above eyes
- working memory
- prefrontal lesions result in short-term memory difficulties

Question:
7. hippocampus

,Answer:
connected to amygdala; deep in frontal lobe; part of limbic system
-memory storage; forms links between memories from data received
- conversion of memory trace to LTM lesion results in amnesia + inability to form new long-term
memories
- episodic and semantic memory

Question:
8. amygdala
Answer:
in front of hippocampus bilaterally
- fight or flight; reward
- emotional memory
- memory related to smell and teaste
- episodic and semantic memory
- looks like brain fallopian tybes

Question:
9. parietal lobe
Answer:
A region of the cerebral cortex whose functions include processing information about touch.
- non-verbal memory

Question:
10. temporal lobe
Answer:
A region of the cerebral cortex responsible for hearing and language.
- semantic memory

Question:
11. basal ganglia
Answer:
a set of subcortical structures that directs intentional movements, plays a part in motor control and
refinement, reward system, and emotional gating
- base of the forebrain and top of the midbrain beneath the central cortex; surrounds thalamus
- non-delcarative memory (motor learning)

Question:
12. cerebellum
Answer:
the "little brain" at the rear of the brainstem; functions include processing sensory input and coordinating
movement output and balance
- 3 lobes: posterior, anterior, and flocculondular
- 3 peduncles - superior, middle, and inferior
- non-declarative memory (motor learning)
- receives extensive sensory input, but doesn't discriminate or interpret lesions DO NOT result in paralysis

, Question:
13. superior cerbellar peduncle
Answer:
EFFERENT - output sends information to the thalamus (PMC), brainstem & spinal cord

Question:
14. middle cerebellar peduncle
Answer:
AFFERENT- input receives input from the brainstem & cortex

Question:
15. inferior cerebellar peduncle
Answer:
AFFERENT - input input from spinal cord, brainstem, and vestibular system

Question:
16. Anterior lobe of cerebellum
Answer:
connections to brain steam and spinal cord
- modifications in muscle tone

Question:
17. posterior lobe of cerebellum
Answer:
connections to cortex via brainstem and thalamus
- coordinates, smoothes muscle (synergy)

Question:
18. flocculondular lobe of cerebellum
Answer:
connections to vestibular system
- reflexive balance and equilibrium

Question:
19. Disorders of the cerebellum
Answer:
ataxia tremors (postural, terminal, and action) disdiadochokinesia dysmetria rebound disequilibrium

Question:
20. SENSORY SYS- TEM (Areas)
Answer:
Primary Somatosensory Cortex (PSC) Primary Auditory Cortex (PAC) Primary Visual Cortex

Question:
21. Primary Somatosensory Cortex (PSC)
