Fast micrographia and frontal lobe dysfunction post-traumatic brain injury: insights into pacing impairment and rehabilitation strategy.

Micrographia, characterised by small handwriting, is often linked to Parkinson's disease, but also resulted to injured brain lesions. The left-handed women in her 20s developed 'fast micrographia' after a traumatic brain injury from a traffic accident, showing bilateral subdural haematomas and frontal lobe contusions, but she had no paralysis and extrapyramidal symptoms. Neuropsychological tests showed reduced processing speed and memory deficits, aligning with frontal lobe damage. A 3-month handwriting training programme improved performance with cues, but issues persisted without them. This case highlights the complexity of fast micrographia and the need for targeted rehabilitation strategies and further research.
