Neurology® Podcast Changes in Cerebral and Hypothalamic Structure With Sleep Dysfunction in Patients With Genetic FTD
Jan 13, 2025
Dr. Simon Ducharme, a senior author from McGill University, dives into intriguing findings on sleep dysfunction related to genetic frontotemporal dementia (FTD). He discusses the impact of MAPT gene mutations on sleep patterns and emphasizes the role of genetic testing for early diagnosis. Ducharme highlights the association between hypothalamic structural changes and sleep issues, along with the need for effective treatment strategies. He also explores the significance of managing sleep disorders in improving care for FTD patients.

Episode notes
Genetics in FTD
- Genetic mutations are much more common in frontotemporal dementia (FTD) than in Alzheimer's disease.
- About a third of FTD patients carry a pathogenic mutation, making genetic testing crucial.
FTD Diagnosis Importance
- Determining FTD diagnosis is crucial due to its higher genetic implications compared to Alzheimer's or Lewy body dementia.
- This is important for both patient care and potential family planning.
Sleep and Gene Mutations
- Carriers of all three main FTD-related gene mutations experience increased sleep problems throughout life.
- MAPT mutation carriers, however, show sleep changes even before other FTD symptoms appear.
