Does stopping clonazepam (benzodiazepine) use improve memory impairment?

Memory Improvement After Stopping Clonazepam Use

Yes, stopping clonazepam use can improve memory impairment, as benzodiazepines are known to cause memory dysfunction that may persist during use. 1, 2

Effects of Clonazepam on Memory

• Clonazepam, like other benzodiazepines, can cause memory impairment, particularly affecting the formation of long-term memories (anterograde amnesia) 3
• Memory dysfunction is listed as a common adverse effect during clonazepam use and can persist throughout treatment 2
• Benzodiazepines affect memory by impairing the transfer of information from short-term to long-term memory storage 3
• Even low doses of clonazepam (0.25 mg) have been shown to impair memory encoding in experimental settings 4

Memory Recovery After Discontinuation

• Discontinuation of clonazepam may lead to improvement in memory function, though recovery may be gradual 5
• The FDA drug label notes that cognitive impairments, including memory dysfunction, are among the symptoms that can persist during protracted withdrawal syndrome 2
• Some studies suggest modest recovery of certain cognitive deficits emerges at 6 months follow-up after benzodiazepine discontinuation, though performance may remain below baseline 5

Discontinuation Process and Considerations

• Abrupt discontinuation of clonazepam should be avoided as it can precipitate withdrawal symptoms, including seizures 2
• A gradual tapering approach is recommended to minimize withdrawal reactions 2, 1
  • One approach suggests withdrawing 25% of the daily benzodiazepine dose each week, though more gradual tapering may be needed in many cases 1
• A feasibility study on clonazepam deprescription in older adults showed that 81.5% of participants achieved some level of deprescription, with 22.2% stopping completely 6

Potential Withdrawal Symptoms Affecting Cognition

• During withdrawal, patients may experience symptoms that temporarily affect cognition, including:
  • Anxiety, insomnia, irritability, and restlessness 2
  • Protracted withdrawal syndrome may include cognitive impairment that persists beyond 4-6 weeks after initial withdrawal 2

Monitoring and Support During Discontinuation

• Regular monitoring for withdrawal symptoms is essential during the tapering process 1
• Education about the risks and benefits of tapering has been shown to improve success rates in benzodiazepine discontinuation 1
• Alternative therapies may be considered to address the original indication for clonazepam use 1, 7

Important Caveats

• Some studies suggest that cognitive deficits may persist for months after discontinuation, particularly in long-term users 5
• Individual responses to discontinuation vary, and some patients may experience more persistent cognitive effects 5
• If clonazepam was prescribed for REM sleep behavior disorder, symptoms may immediately relapse upon discontinuation 1, 7
