There is a little-known dementia red flag symptom that may be spotted while you sleep.
The disorder affects around two per cent of people over the age of 65 and could foreshadow the chances of later developing brain diseases such as Parkinson's and dementia.
Known as REM sleep disorder, or RBD, the health issue impacts roughly one per cent of the general population. Standing for rapid eye movement, REM impacts a person's dreams, memory, emotional processing, and healthy brain development. This is an important stage in the sleep cycle, with the disorder stopping the body from entering a state of low muscle tone, meaning muscles do not 'act out' dreams.
