Behavioral and Cognitive Response to Selective Serotonin Reuptake Inhibitors in Frontotemporal Lobar Degeneration: A...

Area of Science:

• Neuroscience
• Pharmacology
• Psychiatry

Background:

• Frontotemporal lobar degeneration (FTLD) is a progressive neurodegenerative disorder.
• Behavioral and cognitive symptoms significantly impact patient quality of life.
• Current treatment options for FTLD symptoms are limited.

Purpose of the Study:

• To systematically review the efficacy and efficiency of SSRIs in treating FTLD.
• To analyze the effects of SSRIs on behavioral and cognitive functions in FTLD patients.

Main Methods:

• Systematic literature search using CENTRAL, MEDLINE, and Cochrane Library.
• Inclusion of 11 randomized controlled trials and open-label studies.
• Random-effects meta-analysis of 3 studies using the Neuropsychiatric Inventory.

Main Results:

• Meta-analysis revealed a significant reduction in Neuropsychiatric Inventory scores with SSRI treatment (P=0.01).
• Moderate heterogeneity (I2=62%) was observed among studies.
• No significant publication bias detected (Egger's test, P=0.526).

Conclusions:

• SSRIs are effective in managing behavioral symptoms of FTLD, including disinhibition, irritability, and aggression.
• SSRIs did not show significant improvement in apathy or loss of empathy.
• Cognitive functions may be detrimentally affected by SSRI use in FTLD patients.
