[On the problem of depressive pseudodementia]

Area of Science:

• Geriatric Psychiatry
• Neuropsychology
• Medical Terminology

Context:

• The term "depressive pseudodementia" has been used for decades to describe cognitive impairment in elderly patients presenting with depressive symptoms.
• This term lacks diagnostic clarity and therapeutic specificity, leading to confusion in clinical practice and research.
• Existing diagnostic frameworks require refinement to accurately differentiate between depression-induced cognitive impairment and primary dementia.

Purpose:

• To critically evaluate the term "depressive pseudodementia" and its implications.
• To advocate for the abandonment of ambiguous terminology in dementia research.
• To propose alternative, more precise terms for classifying cognitive impairment in the elderly.

Summary:

• The study critically examines the term "depressive pseudodementia," highlighting its diagnostic and therapeutic ambiguities.
• It argues for discontinuing this term due to its lack of precision in distinguishing between psychopathological symptoms and clinical diagnoses.
• The authors propose using "dementia syndrome" or "cognitive impairment" at the syndromal level and specifying co-occurring conditions (depression, dementia type) at the nosological level.

Impact:

• Adopting clearer terminology will enhance the qualitative differentiation and quantification of cognitive impairment in elderly patients.
• This shift promotes more accurate diagnoses and targeted therapeutic strategies for cognitive disorders in aging populations.
• Improved classification facilitates advancements in dementia research and understanding of its complex interplay with mood disorders.
