Can wearables really track brain health? neurologists warn against overpromising gadgets

Consumer wearables can track wellness signals like heart rate and sleep but cannot diagnose or directly monitor neurological diseases. Neurologists warn that claims about wearables detecting brain disorders are exaggerated; only validated medical tests like MRI, CT, and EEG can assess brain health. Wearables may help track trends or provide alerts for specific conditions but should not replace clinical evaluation or cause unnecessary anxiety.
