In severe cases, it is impossible to hold a pen and write. This disease is often induced by physical fatigue (especially hand fatigue) or nervousness. The more nervous you are, the more afraid you are of poor handwriting, and the more obvious the spasm is. If you do something with your hands that doesn't need careful operation, you will feel calm, operate with ease, and the degree of convulsion will be very light. Even convulsions don't happen. Middle-aged and elderly people are prone to nervous system diseases such as Parkinson's disease or cerebellar ataxia, and symptoms such as finger spasm or tremor may occur after illness. Dysgraphia patients have quick thinking, no hemiplegia, normal fertility, no muscle atrophy, normal reflex and no abnormality in brain CT examination, so they are easy to distinguish from the above nervous system diseases.
