Late-life anxiety disorders.

Area of Science:

• Geriatric Psychiatry
• Clinical Psychology
• Pharmacology

Background:

• Anxiety disorders in the elderly are significantly understudied.
• While full anxiety disorders are less prevalent in older adults, subsyndromal anxiety is nearly as common as in younger populations.
• Mixed anxiety-depression and generalized anxiety disorder are the most frequent late-life anxiety disorders.

Purpose of the Study:

• To review the prevalence, natural course, risk profile, and treatment of anxiety disorders in the elderly.
• To highlight the knowledge gaps in understanding and managing late-life anxiety.
• To discuss current treatment approaches and their limitations in older adults.

Main Methods:

• Literature review and synthesis of existing research on elderly anxiety.
• Analysis of current pharmacological treatments, including benzodiazepines and antidepressants.
• Examination of emerging treatments like gabapentin and atypical antipsychotics.

Main Results:

• Benzodiazepines are commonly used but carry significant liabilities in the elderly.
• Antidepressants are widely prescribed, yet no randomized controlled trials for anxiety disorders exist in this population.
• Gabapentin and low-dose atypical antipsychotics are increasingly used, with ongoing studies.

Conclusions:

• Treatment of late-life anxiety currently relies on extrapolating data from the general adult population.
• There is a critical need for dedicated research and clinical trials for anxiety disorders in the elderly.
• Further studies on atypical antipsychotics and other novel treatments are essential for evidence-based geriatric anxiety management.
