Not sleepwalking! Punching and kicking in sleep may be early sign of dementia, doctors say

In a significant development for neurodegenerative disease awareness in Taiwan, physicians at the New Ying Hospital have identified a critical link between unusual sleep behaviors and the early onset of dementia, particularly Lewy body dementia.

Clinical observations reveal that some patients exhibit aggressive actions during sleep—punching, kicking, and even attacking others—which families often misinterpret as mere nightmares or sleepwalking. However, detailed neurological assessments confirm these behaviors are indicative of REM sleep behavior disorder (RBD), a condition strongly associated with neurodegenerative diseases like Lewy body dementia and Parkinson's.

This finding is crucial because RBD often manifests years before more commonly recognized symptoms, such as memory loss, begin to appear. Dr. Wang Wei-jen of the Neurology Department at New Ying Hospital emphasizes that this sleep disturbance is not just a sign of poor sleep quality but a tangible indicator of underlying brain degeneration. This early warning sign has been under-recognized in public health education, leading to delayed diagnoses.

As Taiwan rapidly ages, the shift from reactive treatment to proactive early identification and intervention for dementia is paramount. The hospital's establishment of a dementia care center aims to integrate various medical resources to identify high-risk individuals through atypical symptoms like RBD. This approach is vital for mitigating the disease's impact on patients and their families, and for strengthening Taiwan's community care network. We urge the public to be vigilant and seek professional evaluation if they or their loved ones exhibit such sleep disturbances.
