# A Case of Non-ketotic Hyperglycemic Hemichorea-Hemiballismus in a 54-Year-Old Male Individual With Type 2 Diabetes Mellitus

## TL;DR

A 54-year-old man with type 2 diabetes developed a rare neurological condition due to high blood sugar, which improved with strict blood sugar control.

## Contribution

This paper presents a new clinical case of non-ketotic hyperglycemic hemichorea-hemiballismus managed successfully with glycemic control.

## Key findings

- The patient showed significant symptom improvement after two months of strict glycemic control.
- Complete recovery is expected within six months of onset with proper management.
- The case highlights the importance of early diagnosis and blood sugar control in this rare condition.

## Abstract

Non-ketotic hyperglycemic hemichorea-hemiballismus syndrome is a rare neurological condition associated with hyperglycemia from uncontrolled type 2 diabetes mellitus. The disease is diagnosed via clinical presentation, laboratory evaluation, and neuroimaging. With a prompt diagnosis, glycemic control is initiated as the mainstay of treatment. Additional management of chorea symptoms can be completed with neuroleptics. Here, we report a case of a 54-year-old male individual presenting with unilateral, involuntary, and uncontrollable muscle contractions secondary to non-ketotic hyperglycemia. He was managed with strict glycemic control only. Significant improvement in symptoms was noted two months after diagnosis. A complete recovery is expected within six months of onset.
