Movement disorders 2 Flashcards
Nature of movement in “Flapping Tremor” asterixis
- Hold arms up with palms forward and tell patient to “stop”: see tics of hands.
- Not frequent, seen mostly in young people
“Flapping Tremor” asterixis: associated disease
Wilson’s Disease, liver failure, uremia / kidney failure (only Wilson’s results in copper problems, the others involve other toxins)
cause of “Flapping Tremor” asterixis
Copper accumulation in the lentiform nucleus causing basal ganglia degeneration
treatment for “Flapping Tremor” asterixis
chelating agents such as penicillamine
nature of movement of tics
- Brief, intermittent movements or sounds
- Sudden, abrupt, transient
- Repetitive, coordinated
- Vary in intensity
- Repeated at irregular intervals
- May resemble gestures, normal behavior
- Sometimes suppressible
- May look like a voluntary movement
associated diseases with tics
tourettes
cause of tics
- SLITRK1 Gene on chromosome 13 (one patient only)
- AD in other cases
- Otherwise idiopathic
meds to treat tics
- Clonidine (anti-HTN)
- SSRIs (for OCD)
- Neuroleptics
- Tetrabenazine
- Clonazepam
chorea nature of movement
Irregular, brief, dancing-like, jerky movements
Move from one body part to another
chorea associated disease
- Huntington’s
- Sydenham chorea (most common type of chorea in kids)
- Chorea Gravidarum
- Lupus: 3rd most common neurologic presentation of lupus
causes of chorea
- HD: CAG repeat
2. Sydenham: post streptococcal immune reaction
dystonia nature of movement
Contraction of muscle agonists and antagonists
Sustained muscle contractions cause twisting, abnormal postures
Can be associated with tremor
cause of primary dystonia
DYT 1-12
cause of secondary dystonia
- Neuro-degenerative disorders
- Ischemic brain injury
- Posttraumatic
- Meds, toxins
Tourette Syndrome is
Motor and vocal tics that are suppressible and last more than 1 year
