echopraxia
mimicking gestures
copraxia
obscene gestures
copralalia
obscene words
echolalia
repetition of words
palilalia
repetition of word/phrase with increasing rapidity
What might you expect to find on Tourette syndrome PE?
normal
Tourette Syndrome: diagnostic criteria
- Motor tics and phonic tics both need to be present (not necessarily together)
- Tics throught the day (or intermittent and last 1 year)
- Characteristics or severity must change over time
- Start before age 18*
What is 1st line treatment of mild, non-disabling tics?
Comprehensive behavioral therapy
What is treatment for moderate to severe tics?
Clonidine or guanfacine
alpha adrenergic agonists
Amyotrophic Lateral Sclerosis: Pathophysiology
Necrosis of the UMN and LMN in the motor cortex of brainstem and spinal cord
What are signs (3) of UMN damage in ALS?
- Spasicity
- Stiffness
- Hyperreflexia
What are the signs (4) of LMN damage in ALS?
- Progressive bilateral fasiculations
- Muscle atrophy
- Hyporeflexia
- Muscle weakness
dysarthria
difficulty speaking (bulbar so LMN)
dysphagia
difficulty swalllowing (bulbar, so LMN)
Which two voluntary muscles are spared in ALS?
voluntary eye muscles
urinary sphincter
What is the first line treatment for ALS?
Riluzole (inhibits glutamate)
-modest benefit, only extends life by up to 6 months
Acute inflammatory demylinating polyradiculopathy of peripheral (LMN)?
Guillian-Barre
Describe the clincal presentation of Guillian-Barre Syndrome
- Symmetric, progressive ascending weakness and parethesias
- DTRs absent/depressed***
- Autonomic dysfunction (ex. arrhthymias, BP instability)
- No atrophy
- Radicular pain
- Ataxia affecting gait out of proportion with muscle weakness
How is Guillian- Barre diagnosed?
Lumbar puncture: HIGH protein in CSF with normal WBC count
“albuminocytologic dissociation”
What needs to be done to classify Guillian-Barre?
Nerve conduction studies
Are corticosteroids helpful for Guillian barre?
NO
Tx for guillian barre?
- Immunotherapy (IVIG)
2. Plasmaphoresis
What is the recovery sequence for Guillian-Barre?
Bulbar (speech, swallowing)—>LE–>DTR
What are 3 indicators of poor prognosis in Guillian Barre?
- Cranial nerve involvement
- Intubation
- Maximum disability at time of initial presentation
