Understanding the Risks and Implications
Benzodiazepines, commonly referred to as benzos, are a class of medications prescribed for anxiety, seizures, and insomnia. While these drugs can be effective in the short term, a growing body of research raises concerns about their long-term safety in elderly patients. One question is gaining attention: Can benzodiazepines cause dementia?
This article explores the relationship between dementia and benzodiazepines using evidence from several observational studies, systematic reviews, and more to help you understand the risks and how to protect your brain health.
Key Takeaways

How Do Benzos Work?
When someone takes a benzodiazepine medication, it enhances the activity of gamma-aminobutyric acid (GABA), a neurotransmitter that blocks nerve impulses in the brain.
As central nervous system depressants, benzos produce a calming effect that slows down brain function, helping to reduce anxiety disorders, prevent sleep disorders, and promote rest. This mechanism is central to how benzos produce a sedative or tranquilizing effect.
What Is Dementia?
Dementia refers to a group of symptoms that affect memory, thinking, behavior, and social abilities. It gradually interferes with a person’s ability to perform everyday activities. Dementia diagnosis is typically based on criteria from the Diagnostic and Statistical Manual of Mental Disorders (DSM-5).
Alzheimer’s disease is the most common form of dementia, and while no cure exists, symptoms typically start mild and worsen over time.
Although dementia presents differently in individuals, some universal symptoms include:
- Paranoia or suspicious thoughts
- Mood swings or emotional instability
- Confusion or disorientation
- Memory loss and forgetfulness
- Difficulty maintaining conversations
- Sleep disturbances
- Impaired decision-making or problem-solving
Other types of dementia include Lewy body dementia, vascular dementia, and frontotemporal dementia. In many cases, early symptoms overlap with signs of mental health disorders and medication side effects, making diagnosis more complex.
What Do Studies Reveal About the Link Between Benzodiazepines and Dementia Risk?
Researchers continue to investigate the relationship between chronic benzodiazepine use and the incidence of dementia. While some studies highlight a potential benzodiazepine dementia disorders link, others found little evidence of a causal relationship, and some warn that lower cognitive ability raises the risk of benzodiazepine use in adulthood.
The Caerphilly Prospective Study by Gallacher et al. in 2011 found a significant positive link between benzo use and dementia, with the strongest relationship observed for cumulative use over four years.
Prospective cohort studies found that participants who took prescribed benzodiazepines, especially for extended periods, were more likely to develop dementia than those who did not. For instance, a statistically significant association was reported in a 2014 BMJ study, where researchers observed up to a 51% increase in the risk of dementia following benzo usage, especially among long-term users.
However, other researchers argue that early symptoms of dementia, such as anxiety or sleep disturbances, might lead to benzodiazepine prescriptions, complicating efforts to determine a true causal relationship. To address these confounding variables, sensitivity analyses were used to adjust for pre-existing conditions and compare outcomes more accurately.
When comparing groups of benzo users and non-users, dementia risk is often assessed using standardized cognitive testing, diagnosis criteria, and follow-up evaluations. The results vary, but across multiple reviews, dementia risk compared between long-term users and control groups tends to lean toward a modest to moderate increase in risk.
This growing body of research underscores the importance of caution, especially for dementia prevention in older adults. This then makes it essential for anyone currently prescribed benzodiazepines to work closely with their healthcare provider to evaluate the necessity, dose, and duration of their treatment plan.
Types of Benzos
Benzodiazepines are classified based on how long they act in the body. These include:
- Short-acting benzos: Quick onset, short duration (e.g., Alprazolam – used for anxiety and panic disorders)
- Intermediate-acting benzos: Moderate duration (e.g., Lorazepam – used for anxiety and seizures)
- Long-acting benzos: Remain active for an extended period (e.g., Diazepam – used for anxiety, muscle spasms, alcohol withdrawal, and seizures)
Each type varies in duration, potency, and specific clinical use.
Possible Effects of Using Benzos
While benzodiazepines can relieve symptoms in the short term, long-term benzodiazepine users may face serious side effects. These can vary based on the dosage, duration, and the individual’s health.
Common adverse effects may include:
- Syncope
- Tremors
- Drowsiness
- Confusion
- Respiratory depression
- Headache
Long-term effects may include:
- Cognitive decline
- Memory loss
- Addiction or dependence
These effects are particularly concerning for elderly patients, whose bodies metabolize drugs more slowly and may be more sensitive to side effects.
Benzos Withdrawal Symptoms
Withdrawal from benzodiazepines can occur even with prescribed use, especially if taken for an extended period. Tapering off the medication gradually, under medical supervision, is essential to reduce risks.
Common benzo withdrawal symptoms include:
- Anxiety and irritability
- Muscle pain or stiffness
- Dizziness or headaches
- Sleep issues or nightmares
- Hallucinations or paranoia
- Seizures (in severe cases)
Withdrawal symptoms can sometimes mimic early signs of dementia, making it important to distinguish between the two with professional help.
Signs of Benzos Overdose
An overdose can occur with intentional misuse or accidentally, particularly when benzos are combined with alcohol or other depressants.
Between 2019 and 2020, emergency visits for benzodiazepine overdoses rose by 23.7%, involving opioids in 34.4% of cases and without opioids in 21.0%. Overdose deaths related to benzodiazepines increased by 21.8% for prescription and 519.6% for illicit use from April to June 2019 to the same period in 2020. In the first half of 2020, 92.7% of benzodiazepine overdose deaths involved opioids.
Symptoms of benzodiazepine overdose and toxicity include:
- Extreme confusion
- Trembling or shakiness
- Slurred speech
- Severe drowsiness or sedation
- Aggression or agitation
- Loss of consciousness or coma

What Should You Do If You’re Taking Benzos?
No one should take benzodiazepines without a doctor’s prescription. If you’re prescribed benzos, especially as a senior or someone with a family history of dementia, discuss your risks in detail with your healthcare provider.
Make sure to:
- Share any family history of dementia or alzheimer’s disease
- Disclose all medications and health conditions
- Report any changes in memory, mood, or behavior
- Ask if non-benzodiazepine alternatives or lower doses are appropriate
It’s equally important for caregivers and loved ones to observe and document any unusual changes in the person taking benzos.
If there’s ever a suspicion of misuse, overdose, or cognitive changes, seek medical help immediately.
Frequently Asked Questions
Are certain benzodiazepines more likely to cause dementia than others?
Some studies suggest that long-acting benzodiazepines (like diazepam) may pose a higher dementia risk than short-acting ones.
However, the overall cumulative dose and duration of use appear to be more important factors than the specific medication.
Does long-term benzodiazepine exposure pose a greater dementia risk for individuals with pre-existing health issues or mood disorders?
Individuals with certain risk factors, such as a chronic illness or existing mental health conditions affecting memory and mood regulation, may be at higher risk for long term dementia risk from prolonged benzodiazepine exposure.
These underlying vulnerabilities can interact with the effects of benzodiazepines, potentially increasing the likelihood of cognitive decline beyond that associated with the drug’s impact on healthy brains or its potential to induce physical dependence.
Can benzodiazepine use affect younger adults’ brain health long term?
While most research focuses on the elderly population, prolonged benzodiazepine use in younger adults may still affect brain function, especially with high doses or misuse.
Do anticholinergic drugs and benzodiazepines increase dementia risk when combined?
Studies have found anticholinergic drug usage to be associated with increased risk of dementia. With this already being established, there might also be a risk of dementia if an anticholinergic drug is combined with benzodiazepine use.
Can stopping benzodiazepines improve memory and cognitive function?
In some cases, yes. Gradual withdrawal under medical supervision may help mild cognitive impairment caused by benzos, as studies have found.
Can benzodiazepines interfere with dementia medications?
Generally, clinicians tend to avoid prescribing benzodiazepines to older people with dementia because these drugs are linked to fall-related injuries and cognitive decline.
Does gender affect the dementia risk from benzodiazepine use?
Current data is mixed. However, studies suggest female patients may be more vulnerable to dementia. However, more research is needed to confirm a gender-based risk difference.
Conclusion
The relationship between long term benzodiazepine use and dementia risk is a complex and evolving area of research. While some studies have identified a concerning association, particularly with extended use and higher doses, the challenge of distinguishing causation from correlation remains.
It’s crucial to acknowledge that the conditions for which benzodiazepines are prescribed, anxiety, insomnia, and depression, are themselves linked to an increased risk of dementia.
Nevertheless, the growing body of evidence strongly suggests that caution is warranted, especially in older adults and those with existing risk factors for dementia.
