Demoralization in Parkinson disease

Area of Science:

• Neurology
• Psychiatry
• Clinical Psychology

Background:

• Demoralization is a distinct clinical entity characterized by an inability to cope.
• It is crucial to differentiate demoralization from depression, as treatment strategies differ.
• Understanding demoralization's prevalence in Parkinson's disease (PD) is essential for targeted interventions.

Purpose of the Study:

• To investigate the prevalence of demoralization in individuals with Parkinson's disease (PD).
• To identify features associated with demoralization in the PD population.
• To compare demoralization rates between PD patients and healthy controls.

Main Methods:

• Prospective recruitment of PD patients and controls from movement disorder clinics and the community.
• Demoralization assessed using the Diagnostic Criteria for Psychosomatic Research Demoralization questionnaire or Kissane Demoralization Scale (≥24).
• Depression assessed using the Patient Health Questionnaire-9 (≥10); logistic regression analyzed associations.

Main Results:

• Demoralization was present in 18.1% of PD patients versus 8.1% of controls (p=0.05).
• PD patients showed a higher likelihood of demoralization (OR 2.60, p=0.051), associated with younger age and single status.
• In PD patients, demoralization correlated with younger age and motor impairment (UPDRS Part III score).

Conclusions:

• Demoralization is a common condition in Parkinson's disease, often linked to motor dysfunction.
• Demoralization is distinct from depression, marked by an impaired ability to cope.
• Identifying demoralization in PD patients is critical for implementing appropriate and distinct treatment plans.
