The hallmark signs of Parkinson’s disease include movement disorders such as slowness of movement (bradykinesia), inability to move (akinesia), resting tremors, parkinsonian gait and muscle rigidity. Occasionally the disease also causes depression, constipation, speech impairment, sexual dysfunction and dementia. The severity of Parkinson's disease symptoms tend to progress over time.
