Neurology - Studylist 4

basal ganglia or corpus striatum - component of "extrapyramidal motor system"

location and components (caudate, putamen, globus pallidus)
connections
    input from cortex-thalamus, substantia nigra of midbrain (nigrostriatal pathway)
    output to same areas and extrapyramidal descending pathways discussed in spinal cord chapter
basal ganglia disorders
    Parkinson's disease
        what's wrong with the brain (death of DA neurons of substantia nigra), who it is seen in
        what are the symptoms
            bradykinesia
            tremor at rest
            rigidity
            flexed posture
            trouble initiating movements
    treatments
       medications
       pallidotomy
       thalamotomy
       deep brain stimulation
       stem cell implants
    cognitive deterioration or "bradyphrenia" 
    Parkinson's disease dementia or Lewy Body dementia

Huntington's disease
        what's wrong with brain (loss of neurons in caudate/putamen and cortex; who gets it)
        CAG repeats
        what are the symptoms
            chorea
            athetosis
            dementia
          treatments

Tourette's syndrome
        symptoms
        treatments
        correlation with other disorders

cranial nerves
    the 12 pairs of nerves
    what chunk of brain each connects to
    what each nerve does
    what you wouldn't be able to do if each were damaged
trigeminal dermatomes (opthalmic, maxillary, mandibular)
cranial nerve related problems
    palsies or paralysis of 3 nerves related to eye movement
    trigeminal neuralgia (tic douloureux)
    Bell's palsy (facial paralysis)
    Meniere's disease
   
thalamus
    general structure and location
    major divisions and functions
    functions as a relay station for messages heading to cortex

"specific nuclei" of thalamus
    those with sensory functions such as
        ventral-posterior (VP thalamus) touch
        lateral geniculate - vision
        medial geniculate - audition
    those with motor functions
        VA and VL
    regions of cortex specific nuclei send their messages to

"nonspecific nuclei" connect to association areas of cortex and/or limbic structures
    anterior nuclei
    medial nuclei
    intralaminar and reticular nuclei
    kinds of functions the nonspecific nuclei are involved in
seizure vs epilepsy
"primary" vs "secondary" epilepsy
generalized vs partial/focal epilepsy
characteristics of different types
    generalized tonic-clonic or grand mal seizures
    petit mal  or absence seizures
    simple partial seizures
    complex partial seizures
        temporal lobe or psychomotor seizures
aura
automatisms
treatments for epilepsy
status epilepticus
