Dementia can develop for many reasons — including age, genetics, brain changes, lifestyle factors, or long-term health issues. According to Dementia UK, the condition begins when brain cells become damaged and can no longer communicate well. Over time, this leads to memory loss and shrinking of certain areas of the brain.

A recent study published in Regional Anesthesia & Pain Medicine has raised new questions after researchers observed a possible link between the widely used medication gabapentin and a higher risk of dementia.
