What this trial studies

This clinical study investigates the relationship between sleep quality and neuropathic pain in patients undergoing treatment with pregabalin. It involves 40 participants aged 18 to 75 with chronic moderate to severe pain due to peripheral neuropathy, who are divided into two groups based on their insomnia severity. The study assesses sleep through various methods, including sleep diaries and polysomnography, before and after one month of stable pregabalin dosage. Additionally, brain connectivity and volume changes will be evaluated using fMRI to understand the impact of pain and sleep disturbances.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 to 75 with chronic peripheral neuropathy and moderate to severe pain.

Not a fit: Patients with psychotic depression or significant bipolar disorder, or those who cannot undergo fMRI, may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved treatment strategies for neuropathic pain patients suffering from sleep disturbances.

How similar studies have performed: Previous studies have shown promising results in the efficacy of pregabalin for neuropathic pain, but this specific focus on sleep quality is relatively novel.
