DOPA-sparing strategy in the treatment of young onset Parkinson's disease.

Context: Late onset Parkinson's disease (LOPD) is a neurodegenerative disorder afflicting individuals of ages 60 and older. However, 5-10% of cases can begin earlier between the ages 20 to 40, and are classified as young onset Parkinson disease (YOPD).

Aim: In turn, this study aims to observe the trend in the choice of drug administered to patients with both YOPD and LOPD, with particular emphasis on this trend in its relation to the practice background of the neurologist.

Prevalence of essential tremor in an idiopathic Parkinson's disease patient population.

Essential tremor (ET) and Parkinson's disease (PD) tremor differ in type, frequency and distribution. Despite being two separate disorders, there have been cases reported of comorbidity for ET-PD. Studies have reported an increase in the incidence of ET in relatives of patients with PD, yet the risk of developing PD in ET patients has not been thoroughly investigated.

Factors associated with the development of impulse compulsive disorders in Parkinson patients.

Objective: The aim of this study is to identify the prevalence of impulse compulsive disorder (ICD) in Parkinson's disease (PD) patients and to study potential associative factors that may be related to the onset of ICD while on parkinsonian medications.

Method: The study was conducted in two parts. In Part A, the prevalence of ICD in 140 PD patients was first assessed, followed by identifying any common variables that may be associated with the development of ICD.
