Introduction: In addition to the motor disturbances experienced by the patients suffering from Parkinson's disease (PD), several non-motor symptoms also affect the PD patients: neurobehavior symptoms (dementia, depression, anxiety, psychosis), autonomic (postural hypotension, urinary symptoms, gastro intestinal symptoms, diaphoresis), sleep disorders (insomnia, somnolence, REM sleep behavior disorder, apnea), sensitive-motor (fatigue, diplopia, restless legs syndrome), and sensory symptoms.
Development: We review the most relevant about sensory symptoms in PD: visual dysfunction, olfactory dysfunction, taste, hearing loss, and pain and other sensitive associate symptoms.
Conclusions: Pain is frequently observed in patients with PD, being its prevalence high and probably infra diagnosed. Its identification and classification is very important for a correct treatment. Hyposmia is a common symptom in PD and could be a predictor of future PD. Visual dysfunction and hearing dysfunction among others must be considered in patients with PD.
