SUMMARY
TIP: The main signs can be remembered by the mnemonic DDANISH
1. Dysdiadokinesia: inability to perform and sustain a series of rapidly alternating muscle movements (typically flipping one hand rapidly in the palm of the other).
2. Dysmetria: disturbance in the trajectory during active movement resulting in hypometria (under-shooting) or hypermetria (over-shooting).
3. Ataxia: defined as incoordination of muscle movement that is not due to paresis, alteration in tone, loss of postural sense, or the presence of involuntary movements.
4. Nystagmus: a repetitive, involuntary oscillation of the eyes. The patient may also complain of blurred vision.
5. Intention tremor: a wide tremor during voluntary movements, such as holding out the hands.
6. Slurred speech: speech may be imprecise, slow and distorted.
7. Hypotonia: patient may have decreased muscle tone on the side of the lesion.
