Myotonic dystrophy type 1 (DM1) can cause brain white matter lesions and stroke-like episodes, even without cardiac issues. This case highlights DM1 as a potential cause of unexplained neurological events.
Area of Science:
- Neurology
- Genetics
- Dermatology
Background:
- Myotonic dystrophy type 1 (DM1), also known as Curschmann-Steinert disease, is linked to brain white matter lesions.
- Cardiac involvement and cardioembolic strokes are recognized complications in DM1 patients.
Observation:
- A 40-year-old female presented with recurrent stroke-like episodes, including dizziness, nausea, and right arm numbness.
- Cerebral MRI revealed extensive white matter lesions without evidence of acute infarction or enhancement.
- Electromyography (EMG) detected myotonic discharges, leading to genetic testing.
Findings:
- Genetic analysis confirmed DM1 with 200 ± 10 CTG repeats in the DMPK gene.
- This case represents the first documented instance of DM1 presenting with stroke-like episodes in the absence of cardiac or vascular abnormalities.
Implications:
- DM1 should be considered in the differential diagnosis of unexplained white matter lesions and stroke-like symptoms.
- This case expands the clinical spectrum of DM1, emphasizing the need for comprehensive neurological evaluation in affected individuals.

Musculoskeletal disorders involve injuries and conditions affecting the skeletal muscles and associated connective tissues. These disorders can arise from acute biomechanical stresses or chronic overuse and can occur across different age groups. Common injuries include sprains, fractures, and muscular strains, often resulting from...
