Parkinson's disease is characterised by motor and non-motor clinical features. The latter may present as pre-motor symptoms several years before the onset of motor symptoms. Pre-motor symptoms have been found to be associated to a later motor onset of Parkinson's Disease.

Parkinson's disease is characterised by motor and non-motor clinical features. The latter may present as pre-motor symptoms several years before the onset of motor symptoms. Pre-motor symptoms have been found to be associated to a later motor onset of Parkinson's Disease.
The overall frequency of pre-motor symptoms was 76%. Among the most prevalent
symptoms were depression (38%), sleep disorders (37%) and anxiety (36%). The time prior
to motor onset was greatest for constipation (9 years) and pain (8 years).People with more than two pre-motor symptoms had a later age
at motor onset when compared to people without pre-motor
symptoms (56 v 52). Late onset patients had a higher frequency
of pre-motor symptoms (79% v 65% in early onset) and worse
symptoms than early onset. Females reported a higher number
of pre-motor symptoms (1.9 v 1.4). Anxiety lead-time was
greater in tremor-dominant compared to bradykinetic-rigid
patients (3 years).
Pre-motor symptoms load is associated to a later motor onset of PD. Pre-motor symptoms are
more frequent in subjects with late onset Parkinson's disease. Female subjects report a higher
number of pre-motor symptoms, depression and anxiety being the most common.
