Hyperglycemia: an unusual cause for hemichorea

Area of Science:

• Neurology
• Neuroscience
• Endocrinology

Background:

• Hemichorea is a rare neurological movement disorder.
• It is characterized by involuntary, purposeless, hyperkinetic movements.
• Oxidative stress and subsequent neurodegeneration of the dentate nuclei and striata are implicated in its pathogenesis.

Observation:

• This report describes a rare case of hemichorea.
• The patient is an adult female with a history of diabetes mellitus.
• The presentation occurred in the context of diabetes, a condition not typically associated with hemichorea.

Findings:

• The case highlights an unusual manifestation of a rare neurological disorder.
• It underscores the potential link between metabolic disorders like diabetes and neurodegenerative processes.
• The neurodegenerative aspect involves the dentate nuclei and striata.

Implications:

• This case may prompt further investigation into the role of oxidative stress in diabetic neuropathy.
• Understanding this association could lead to novel therapeutic strategies for both hemichorea and diabetic complications.
• It emphasizes the need for comprehensive neurological assessment in diabetic patients presenting with movement abnormalities.
