Noticeable changes in weight are common in those with Parkinson's disease and new research looks into why this takes place.
Experts from the International School of Advanced Studies (SISSA) analysed how some of the symptoms of the neurological condition could bring about these incorrect eating habits - especially ones that aren't related to movement.
For instance, depression, cognitive impairment, sensory disruptions and the inability to feel pleasure can cause individuals to either eat excessively or lose interest in food.
These weight changes can bring further problems to those with the condition and so it is important to try to tackle them. While some can shed pounds, others can add up to ten kilograms to their body weight after deep brain stimulation, a procedure that tries to curb the symptoms.
First author of the study Marilena Aiello said: "Awareness of the roles played by the different factors is in fact crucial for devising interventions aiming to minimise the effect of the deficits and restore normal weight levels in individuals.
