EpistemisDepressive pseudodementia
Specialty: Psychiatry.
Why it occurs
- Major depressive disorder in the elderly (geriatric depression with predominantly cognitive expression)
- Bipolar disorder (severe depressive phase with extreme bradypsychia)
- Severe post-traumatic stress disorder
- Dissociative disorders
Initial workup
Mini-Mental State Examination (MMSE) or Montreal Cognitive Assessment (MoCA), where the patient with pseudodementia typically answers "I don't know" to difficult questions rather than making confabulation errors (as occurs in true dementia); Yesavage Geriatric Depression Scale (GDS); Brain MRI to quantify hippocampal atrophy or small vessel vascular lesions; levels of TSH, vitamin B12 and folic acid.
red flags
Coexistence with severe malnutrition due to extreme apathy, hygienic neglect that endangers health, or ideation of passive autolysis (letting oneself die by refusing food and water).
Standard management
- Sertraline — SSRI with excellent cardiovascular safety profile and few drug interactions in the elderly
- Vortioxetine — antidepressant with multimodal action that directly promotes cognitive recovery in depressed patients
- Venlafaxine or Duloxetine — if a broad spectrum approach is required
- Methylphenidate at low doses (in very weakened elderly people under strict cardiac control to accelerate the antidepressant response and initiate cognitive reactivation).
