Comorbidity and retirement in cervical dystonia

Area of Science:

• Neurology
• Psychiatry
• Public Health

Background:

• Cervical dystonia (CD) is a common form of dystonia causing significant functional and psychosocial impairment.
• Non-motor symptoms in CD patients substantially affect their quality of life.

Purpose of the Study:

• To investigate comorbidities in primary focal CD patients in Finland.
• To compare retirement age and reasons for retirement in CD patients versus controls.

Main Methods:

• Retrospective study of 937 adult isolated focal CD patients (2007-2016) using ICD-10 codes and patient records.
• Analysis of retirement data from pension registries.
• Comparison with 3746 age- and gender-matched controls.

Main Results:

• Prominent comorbidities in CD patients included depression (14%), anxiety (7%), and back pain (11%).
• CD patients retired significantly earlier (59.0 years) than controls (61.7 years).
• Top retirement diagnoses for CD patients were dystonia (51%), depression (14%), and anxiety (8%); those with anxiety and depression retired earliest.

Conclusions:

• Cervical dystonia significantly reduces working ability and leads to premature retirement.
• Anxiety and depression are key comorbidities that further impair working capacity.
• Increased healthcare resources and integrated psychiatric care are recommended for CD patients to maintain work ability.
