1

Dyskinesia

Impairment in ability to control movements

2

Bradykinesia

Slow movement

3

Akinesia

Inability to initiate movement

4

Rigidity

An increase in resistance to passive movement

5

Chorea

Brief irregular contractions not repetitive or rhythmic but appear to flow from one muscle to another

6

Ballism

Severe chorea, slight movements becoming thrashing motions, odd postures, or leg movements

7

Dysarthria

Any of certain disorders of articulation caused by impairment of the muscles used in speech, such as stammering or stuttering, caused by a nerve defect

8

Allodynia

Condition in which an ordinarily painless stimulus is experienced as being painful

9

Akathisia

Motor restlessness

10

Cataplexy

Muscular weakness resulting in sudden loss of postural tone, often triggered by an emotional stimulus and resulting in falls to the floor

11

Cogwheeling

Ratchet like movement due to superimposition of tremor on rigidity

12

Facial masking

Decreased facial expression due to rigidity of facial muscles

13

Fasciculation

Spontaneous firing of an axon resulting in a visible twitch of all the muscle fibers it contacts

14

Festination

Involuntary tendency to take short accelerating steps in walking that can occur in Parkinson's disease

15

Freezing

Sudden, brief cessation of movement

16

Korsakoff Syndrome

Chronic phase of thiamine deficiency characterized by impairment in establishing new memories and retrieving previous memories, occurring most commonly in alcoholics

17

Myoclonus

Sudden, shock-like, jerking contraction of a group of muscles

18

Oculogyric crisis

Acute dystonic reaction to neuroleptic drugs manifested by sudden sustained twisting of the head and upward deviation of the eyes

19

On-off phenomenon

sudden, unpredictable changes in motor performance by patients on levodopa therapy

20

Palsy

Paralysis of a muscle group

21

Paraplegia

Paralysis of both legs

22

Penumbra

Area surrounding the dense core of irreversibly damaged cells that has preserved ionic homeostasis and reduced neuronal electrical activity but that is capable of recovery

23

Tardive

Symptoms that develop slowly or appear long after inception

24

Tic

Repetitive, stereotyped, simple or complex movements that can be voluntarily suppressed for short periods of time

25

Torticollis

Form of dystonia in which the neck muscles contract involuntarily, causing the head to turn

26

Wearing off phenomenon

Waning of the effects of a dose of levodopa prior to the scheduled time for the next dose, resulting in decreased motor performance

27

Fluent aphasia

Impairment of language comprehension including impaired repetition due to lesion of the posterior left superior temporal gyrus

28

Athetosis

Twisting and writhing movements

29

Dystonia

Sustained muscle contractions causing twisting and repetitive movements or abnormal postures
