A Patient with Multiple System Atrophy-Parkinsonian Type Presenting with Progressive Micrographia.

ABSTRACT

Herein, we present the case of a 57-year-old male patient who was admitted to our center due to progressive writing difficulty and slowness of his right hand over the last 3 years. In conclusion of the clinical and laboratory workup, a diagnosis of multiple system atrophy (MSA) was established. Our report on progressive micrographia (PM) constitutes a crucial sample remarking on this intriguing manifestation in another disease subtype of MSA, which differs from Parkinson's disease in terms of the clinical and pathophysiological processes. We think that further studies are warranted to clarify the significance of this entity in movement disorder in clinical practice and to reveal the underlying neural mechanisms.
