Tremors

relatively rhythmic oscillaotry movments, which may be roughly subtiviided into three groups

3 groups of tremors

resting tremors (static)

Postural tremors

Intention Tremors

3

Resting (static) tremors,
When are they most prominent?
When do they decrease?

most prominent at rest, may decrease or disappear with voluntary movement


common, relatively slow, fine, pill-rollign tremor of parkinsonism,

4

What type of tremor is Parkinsonian? waht is rate

Resting (static) tremors

5

What are Postural (Action) tremors . When do they appear

appear when the affected part is actively maintaining a posture

6

Examples of postural (action) tremors

examples include fine rapid tremor for hyperthyroidism

tremors of anxiety and fatigue
benign essential (sometimes familial tremor)

tremor may worsen, somewhat with intention

7

What are intention Tremors? when are they absent? when do they get worse

absent at rest

appear with activity

get worse as target is neared

8

what is cause of Intention Tremor

disorders of cerebellar pathwyas,

Multiple Sclerosis (MS)

9

What is Oral-Facial Dyskinesias

rhtymic, repetitive, bizarre movements that chiefly involve face, mouth, jaw, tongue

10

what does patient do if they have oral-faical dyskinesis

grimacing, pursing of lips, prtrustion of tongue, opneigna dn closing of mouth, deviation of jaw

11

cause of oral-facial dyskinesias

may be late complication of psychotropic drugs sucha s phenothiazines, (tardivee dyskinesias)

occur in long-stanidng psychoesies in some elderly indivudals, and in some edentulous persons

12

Athetosis

athetoid moevemtns are slower and more twisting and writhign than chorifoemr movmvents, and ahve larger ampltiudes

most commonly invovle face and distal extremities

foten ass with spasticticy

13

cause of athetoises

cerebral pasly

14

What is Dystonia

similar ot athetoid movemetns, but invovle larger protions of the body, inclduign trunk

Groeque, twisted postures may results

15

Cause of Dystonia

drugs such as phenothiazines, priamry torsion dystonia, and spasmodic torticollis

16

What is Chorea

choreiform movments are brief, rapid, jerky, irregular, and unpredictable.

OCcur at rest or interrupt normal coordinated movments

17

how ar different fro Chorea

unlike tics, they seldome repeat themselves.

The face, head, lower arms, and hands are often inovlved

18
