What Is Micrographia with Parkinson’s Disease?

Micrographia and Parkinson’s Disease – When Handwriting Tells a Story
One of the lesser-known but deeply personal symptoms of Parkinson’s disease is micrographia—a condition that causes handwriting to become abnormally small, cramped, and difficult to read. For many people living with Parkinson’s, the act of writing becomes frustrating and even emotional, especially when once-clear penmanship begins to shrink and fade.

But what causes micrographia, and what can be done to help manage it?

​What Is Micrographia?
Micrographia is a neurological symptom associated with Parkinson’s disease (PD) and other movement disorders. It literally means “small writing.” People experiencing micrographia often notice that their handwriting becomes progressively smaller and more crowded as they write across a page.
This isn’t simply a change in penmanship—it’s a reflection of how Parkinson’s affects the fine motor control and coordination needed for writing.

Why Does It Happen?
In Parkinson’s, the brain produces less dopamine, the chemical responsible for sending signals that control movement. As dopamine levels decline, tasks that require precise, repetitive movements—like writing—become more difficult.
​
Muscles may not respond as quickly or accurately, and the brain’s “motor planning” can break down. As a result, handwriting shrinks, becomes illegible, or trails off entirely.

Signs of Micrographia
Common signs include:

• Letters become smaller and closer together over the course of a sentence.
• Writing may begin at a normal size and then gradually shrink.
• Text may slant, be shaky, or become unreadable.
• The effort required to write increases, causing fatigue or frustration.

​Micrographia may appear early in the course of Parkinson’s and can sometimes even be a clue in diagnosis.

Can Micrographia Be Treated?
While there is no cure for micrographia, it can be managed. Occupational and physical therapists often use targeted writing exercises to improve legibility and hand control.
​
Speech-language pathologists who specialize in Parkinson’s (such as those trained in the LSVT BIG and LSVT LOUD programs) may also help retrain the brain and body to perform larger, more purposeful movements—including handwriting.

Technologies such as tablets or voice-to-text software can also be helpful, especially when fine motor skills decline.
