Treatment involves removing the drug

16
Q

What is acute Akathisia?

A

Feeling of restlessness and an inability to sit still.

17
Q

What is neuroleptic Malignant Syndrome?

A

Autonomic dysfunction, fever, rigidity, akinesia, and altered mental status resulting from use of antipsychotics.

18
Q

What are two systemic conditions involved with Neuroleptic Malignant Syndrome and what can they lead to?

A
  1. Acidosis: caused by accumulation of CO2 from constant muscle contraction, can lead to anything from hyperventilation to coma.
  2. Myoglobinuria: can clog the kidney and lead to kidney failure
19
Q

Name two drugs that can treat Neuroleptic Malignant Syndrome.

A
  1. Bromocriptine: DA agonist allows muscles to relax

2. Dantrolene: acts on sarcoplasmic reticulum and ryanodine receptor to relax muscles

20
Q

What causes Sydenham Chorea (St. Vitus Dance)?

A

Young patients with an immature BBB become infected with Strep. pyogenes which progresses to rheumatic fever. The Abs made against the strep cross the BBB and target the Subthalamus and caudate nuclei.

Patients present with standard chorea symptoms: dance-like movements, darting tongue, facial grimacing

21
Q

What are 4 treatments for Sydenham Chorea?

A
  1. Sedatives
  2. Phenothiazines (phenothiazine, tetrabenazine), haloperidol
  3. Valproic Acid
  4. IV IgG to shut down immune system
22
Q

What brain structure most notably atrophies in Huntington Chorea?

A

Caudate Nucleus

23
Q

What 3 medications can be used to treat HD?

A
  1. Haloperidol
  2. phenothiazine
  3. Tetrabenazine
24
Q

What causes Hemiballism?

A

Some kind of contralateral subthalamic lesion: vascular, hemorrhage, tumor, iatrogenic

Can be bilateral.

25
Q

What are 3 drugs used to treat Hemiballism?

A
  1. Haloperidol
  2. Tetrabenazine
  3. Phenothiazine
    (same as the choreas)
26
Q

What condition makes treating Tics in children difficult?

A

Attention Deficit Disorder

27
Q

What is required to diagnose Gilles de la Tourette Syndrome?

A
  1. Multiple Tics
  2. Vocalizations

(these patients also have sexual impulses)

Q

What is the biochemical cause of Tourette Syndrome?

A

Anti-DNAase B antibodies
-hereditary

Some have dysregulation of DA or an absence of the protein Dynorphin.

29
Q

What are some medications used to treat Tourette Syndrome?

A
  • clonidine
  • haloperidol
  • pimozide (treats tics)
