Depression and Parkinson's disease: a conceptual challenge

Area of Science:

• Neuroscience
• Psychiatry
• Medical Humanities

Background:

• Depression is a common comorbidity in Parkinson's disease (PD).
• Misunderstandings regarding the nosology and etiology of depression in PD persist.
• The conceptual framework for understanding this relationship requires clarification.

Purpose of the Study:

• To conceptually explore the relationship between Parkinson's disease and depression.
• To address semantic confusions and the mind-body distinction impacting PD-depression understanding.
• To propose an integrated neuropsychiatric approach for diagnosis and treatment.

Main Methods:

• Literature review focusing on conceptual, phenomenological, and therapeutic aspects.
• Analysis of semantic confusions and the mind-body dualism in PD research.
• Conceptual discussion of integrated diagnostic and therapeutic strategies.

Main Results:

• Semantic confusion has contributed to misunderstandings of PD-depression nosology.
• The erroneous mind-body distinction has hindered accurate etiological understanding.
• Current conceptualizations impede effective diagnosis and treatment strategies.

Conclusions:

• An integrated neuropsychiatric approach is necessary for improved diagnosis of depression in PD.
• Revising conceptual frameworks can enhance therapeutic interventions for PD patients.
• Addressing semantic and philosophical underpinnings is crucial for advancing PD research.
