[Late-onset depression : Pathophysiology, diagnostics and treatment]

Area of Science:

• Geriatric Psychiatry
• Neuroscience
• Clinical Psychology

Background:

• Late-onset depression (LOD) is depression first appearing in later life.
• Cognitive deficits are more pronounced in LOD compared to other depressive phases.
• LOD is linked to an increased risk of developing dementia.

Purpose of the Study:

• To define late-onset depression (LOD).
• To explore the relationship between LOD and cognitive deficits.
• To outline diagnostic and treatment strategies for LOD.

Main Methods:

• Detailed medical history and psychopathological observation.
• Physical examination, laboratory tests, EEG, ECG, and MRI of the head.
• Neuropsychological tests to assess cognitive deficits.

Main Results:

• LOD symptoms are similar to other depression phases, but with more severe cognitive impairment.
• Imaging studies reveal reduced gray matter volume and vascular white matter lesions in LOD patients.
• The condition is also termed 'vascular depression' when associated with brain vascular lesions.

Conclusions:

• LOD requires comprehensive diagnostic evaluation, including cognitive assessments.
• Psychotherapy is an effective treatment for late-onset depression.
• Selective serotonin reuptake inhibitors (SSRIs) are the recommended first-line pharmacological treatment for LOD.
