Q

Parksinson pts have difficulty with balance and gait

..at what point in the disease process do you see this?

A

later in disease course

(worrisome if seen early. normally this takes long time)

25
Gold standard tx of Parkinsons?
Levodopa (converted to dopamine in the brain. dopamine itself cant cross BBB)
26
When do you start treating Parkinsons?
When **functional disability** starts \*medication benefit only works for a few years
27
What is a surgical tx option for Parkinsons?
Surgically implanted deep brain stimulation ## Footnote **blocks abnormal signals that cause PD symptoms**
28
Autosomal dominant neurodegenerative disorder **Classic triad: motor, cognitive and psychiatric symptoms** insidious onset, no cure age of onset: 30-50 Fatal in 15-20 years\*
Huntington's disease
29
Primary involuntary movement in Huntington's Disease "the dance"
Chorea
30
What is athetosis? (seen in Huntington's)
Proximal limb writhing
31
Involuntary, irregular, rapid, uncontrolled, excessive movement \*often not noticed by, nor disturbing to, the patient
Chorea
32
Abnormal eye movements Slow or uncoordinated fine motor control Dyarthria Dysphagia Gait disturbance Bradykinesia and rigidity late in course (as chorea peaks and wanes)
Huntington's
33
Psychiatric symptoms: Depression Mania OCD Apathy Anxiety
Huntington's disease
34
Cognitive symptoms: Dysfunction of executive functions Problems with plannig, judgement, emotion, regulation, learning, attention, etc. Cant follow instructions Temper outbursts Difficulty with spatial perception
Huntington's
35
**decreased** GABA **decreased** Ach **increased** dopamine
Huntingtons
36
Excessive number of "CAG" sequence repeats
Huntingtons
37
How do you treat Huntingtons?
Symptomatically (Neuroleptics, Benzos, Dopamine depleting agents)
38
MAJOR potential complication of Huntingtons?
Rhabdomyolysis (breakdown of muscle tissue that releases damaging protein into blood)
39
Inherited neurobehavioral disorder characterized by sudden involuntary, repetitive muscle movements and vocalizations
Tourette's
40
For a diagnosis of Tourette's... Tic episodes several times a day, almost every day, or periodically during period longer than....
1 year
41
Where does Tourette's start/originate?
Head and face (ie blinking, face twitch, head jerk, shrug, neck stretch, sniffing)
42
Meaningless repitition or imitation of movements \*seen in Tourette's patients
Echopraxia
43
Palilalia
repeating one’s own words
44
Repeating heard words-last words spoken by someone else
Echolalia
45
Coprolalia
the involuntary and repetitive use of obscene language
46
movement disorder in which involuntary sustained or intermittent muscle contractions cause twisting and repetitive movements, abnormal postures or both **diagnosed in the young!**
Cerebral palsy
47
Non-traumatic fractures can occur due to extreme hyper flexion or hyper extension
Cerebral Palsy (CP)
48
"burning" sensation generally starts in distal extremities (MC feet) and moves proximally
Neuropathy
49
Hallmark= VERY painful with light touch Hypersensitive ## Footnote **pain out of proportion**
Neuropathy
50
Compression at the superior thoracic outlet resulting from excess pressure places on a neurovascular bundle passing between the anterior scalene and middle scalene muscles

Thoracis Outlet Syndrome
52
Intermittent, progressive chronic disorder involving aberrant firing of trigeminal nerve- **usually 2nd and 3rd branches** Unilateral lancing paroxysmal facial pain
