Transcript of Mini Cases in Movement Disorders

Detailed Description:
Case 1 - Kenny
- Kenny, a teenage boy
- experienced compulsions and uncontrollable facial and body movements and a vocal tic
- began experiencing symptoms from a young age, but got better as he got older; symptoms worsen under stress
- frequent blinking and lip puckering; compulsions to touch parts of his body; compulsions to wash hands
- likely has
Tourette Syndrome

Detailed Description:
Case 6 - Jim
Tourette Syndrome
Movement Disorders
Prior Knowledge:
Case 1
Kenny most likely has
Tourette Syndrome
Motor and verbal tic(s)
, both of which have occurred for at least a year, and had to have occurred before 18
co-morbid with ADHD and/or OCD
No cure, but tics can be suppressed
Recent research
: MRI parcellation of the frontal lobe in boys with attention deficit hyperactivity disorder or Tourette syndrome
Recent research:
Chronic bilateral thalamic high frequency stimulation (HFS) may be an effective and safe treatment for medically intractable TS in adult patients; unwanted stimulation-induced side effects may occur

Case 2
Jim most likely has
Parkinson’s Disease
Rigidity of muscles, tremors and shaking and a short “shuffling” gait
Either comes from
drug exposure
No treatment, but symptoms can be relieved
Recent research:
Mutation in the α-synuclein gene identified in families with Parkinson's disease
Recent research:
Oxidative processes clearly contribute to the pathology of Parkinson's disease but are probably secondary to some other primary unidentified cause, presumably genetic or environmental
- Jim, a 70 year old university professor
- After taking Serpalan, Jim started to notice uncontrollable hand and arm shaking. After the new prescription, his hands and arms no longer shook, but he now had a shoulder twitch and noticeable tremors in his right arm and leg. Doctor told him it was due to stress. After a relaxing summer off, doctor insisted on neurological exam.
mild voice tremor, mild bradykinesia, mild intention tremor of the arm, rigidity of his limbs and trunk
- At the age of 70 after taking Serpalan
- tremors on the right side of his body
- very likely has
Parkinson’s disease

- a branch of psychology that analyzes how the brain and neurotransmitters influence our behaviors, thoughts and feelings

Frontal Lobe
-contains the
primary motor cortex
, which contains a map of the body areas that can be voluntarily controlled
premotor and supplementary motor areas
that are involved in movement planning
-control is
(hemispheres control opposite body side)

Motor Cortex
- controls voluntary movements

Basal Ganglia
-a region part of the gray matter within the brain
-aids in voluntary movement

- a chemical messenger that carries, boosts and modulates signals between neurons and other cells in the body
Movement Disorders
• Neurological conditions that affect the
speed, fluency, quality, and ease of movement
• Abnormal fluency or speed of movement (called
) may involve excessive or involuntary movement (
) or slowed or absent voluntary movement (
• Associated with pathological changes in the brain especially in the
basal ganglia
• Defects may also lie in the base of the brain or the
-leads to difficulty in walking, locomotion or maintenance of posture and normal body balance
• Movement disorders are widely prevalent and many of them have

Tourette Syndrome
• A tic disorder defined by multiple physical tics and at least one vocal tic
• Areas of the brain involved are the basal ganglia, frontal lobes, and cortex
Parkinson's Disease
• A progressive disease of the nervous system marked by tremor, muscular rigidity, and slow, imprecise movement (
• Chiefly affecting middle-aged and elderly people
• Associated with degeneration of the basal ganglia of the brain and a deficiency of the neurotransmitter
