Agraphia

Loss of, or impaired, ability to write, despite normal functioning of the hand and arm muscles, caused by brain damage. Agraphia can result from damage to any of the various parts of the cerebrum concerned with writing and can therefore be of different types and degrees of severity. Such damage is most commonly due to head injury, stroke, or a brain tumour. Agraphia is often accompanied by alexia (loss of the ability to read) or may be part of an expressive aphasia (general disturbance in the expression of language). There is no specific treatment for agraphia, but some lost writing skills may return in time.
