Can chronic insomnia really lead to dementia?

While we cannot say chronic insomnia directly causes dementia, research shows strong associations. People with chronic insomnia have a 40% increased risk of developing cognitive impairment or dementia. Chronic sleep disruption may impair the brain's glymphatic clearance system, leading to accumulation of amyloid plaques, white matter damage, and accelerated brain aging. The longer insomnia persists, the higher the risk becomes.

How does LENS neurofeedback help with insomnia?

LENS neurofeedback targets the underlying brainwave dysregulation that perpetuates insomnia. It helps normalize overactive beta waves associated with racing thoughts, strengthens sleep-promoting rhythms, and recalibrates the autonomic nervous system. By improving deep sleep quality, LENS may enhance the brain's natural waste clearance (glymphatic) system. Approximately 85% of our clients report improved sleep quality within 8-12 sessions.

What is the glymphatic system and why does it matter for sleep?

The glymphatic system is the brain's waste clearance mechanism that operates primarily during deep sleep. It flushes metabolic waste products, including amyloid-β peptides associated with Alzheimer's disease. Disrupted, fragmented, or insufficient deep sleep impedes this cleanup process, allowing toxic proteins to accumulate over time. This is one key mechanism linking chronic insomnia to increased dementia risk.

At what age should I be concerned about insomnia and dementia risk?

Research suggests that sleep quality in midlife (40s-60s) may forecast brain aging and dementia vulnerability in later years. However, brain health matters at any age. Early intervention for chronic insomnia is ideal, especially if you're over 50, have family history of dementia, or carry genetic risk factors like APOE ε4. The cumulative burden of poor sleep matters more than age alone.

How many neurofeedback sessions are needed for insomnia?

For chronic insomnia, we typically recommend 12-20 LENS neurofeedback sessions. Many clients notice improvements within the first few sessions, with sleep onset time reducing by 25-40 minutes on average. The exact number varies by individual based on how long insomnia has persisted and underlying factors. We track progress objectively and adjust protocols as needed.

Is neurofeedback better than sleeping pills for long-term brain health?

Neurofeedback offers a drug-free approach that addresses the root cause of sleep dysregulation rather than masking symptoms. While sleep medications can provide short-term relief, they don't restore natural sleep architecture and may have side effects with long-term use. LENS neurofeedback helps the brain relearn healthy sleep patterns, with improvements often maintained 6+ months post-treatment. Many clients successfully reduce or eliminate sleep medication under their doctor's guidance.

Does insurance cover neurofeedback for insomnia?

Some PPO insurance plans provide reimbursement for neurofeedback therapy. We can provide documentation for you to submit to your insurance company. Neurofeedback is also eligible for HSA/FSA spending, and we offer payment plans for treatment packages. We recommend calling your insurance provider to verify your specific coverage for biofeedback or neurofeedback services.

Can neurofeedback prevent dementia?

While we cannot claim neurofeedback prevents dementia, addressing chronic insomnia early may reduce one modifiable risk factor. By optimizing sleep quality and supporting the brain's natural clearance mechanisms, neurofeedback may help preserve cognitive function. Research is ongoing, but treating sleep disorders is increasingly recognized as an important strategy for brain health and potentially reducing dementia risk, especially when combined with other lifestyle factors.
