The myotonic dystrophy experience: a North American cross-sectional study

Area of Science:

• Neurology
• Genetics
• Patient-Reported Outcomes

Background:

• Myotonic dystrophy (DM) is a chronic, multisystemic, neurological disorder.
• Patients and caregivers possess unique insights into DM symptoms and unmet needs.

Purpose of the Study:

• To identify and quantify the most important issues experienced by individuals with DM and their caregivers.
• To examine differences in reported needs based on DM type.
• To highlight the most significant challenges faced by the DM population.

Main Methods:

• A North American, cross-sectional study was conducted.
• Surveys were distributed to patients with DM type-1, congenital DM, and DM type-2, as well as their family members.
• Separate surveys were used for patients and caregivers to gather distinct perspectives.

Main Results:

• 1,180 individuals with DM and 402 family members/caregivers completed the surveys.
• Participants reported substantial physical and cognitive symptoms.
• Extensive diagnostic delays and varying clinical phenotypes based on DM type were observed.

Conclusions:

• Myotonic dystrophy presents a significant disease burden with numerous unmet needs.
• The identified needs differ across DM types, reflecting the complex clinical phenotypes of these neurological disorders.
