Parkinson’s Disease – Non-motor Symptom Complex and Comorbidities

Nearly all patients with Parkinson’s disease (PD) experience non-motor symptoms at some stage of the disease.² Psychiatric symptoms are the most frequent non-motor symptoms, reported by approximately two-thirds of patients with PD.² These symptoms may include dementia, ps…

The non-motor symptoms of PD can be grouped into four domains: autonomic (including gastrointestinal, genitourinary, and cardiovascular symptoms), sleep disorders; neuropsychiatric disorders; and sensory and other symptoms (including pain and fatigue).^1-4 Many of these sy…

One of the main principles of caring for patients with PD is to preserve quality of life as much as possible, particularly during the later stages of the disease.¹ Historically, the focus of clinical care has been on the detection and control of motor symptoms, but there …

Although the neuropathology underlying cognitive impairments in PD broadly conforms to what is termed a ‘subcortical’ syndrome, there is considerable inter-patient heterogeneity.⁶ This variation has led to the suggestion that patients with PD and cognitive impairments can…

The MDS diagnostic criteria for MCI in PD represent an attempt to harmonise the various definitions of MCI in PD that have been used in the past.¹ A uniform definition allows identification of:¹

• the clinical characteristics of the earliest stage of PD cognitive impairmen…

One of the problems that researchers have when studying impaired cognition in PD is the wide variation in criteria used to define MCI, which can make comparisons between studies challenging.^1,2 A meta-analysis of studies investigating the prevalence and clinical aspects o…

While developing the new guidelines for diagnosis of dementia in PD, the MDS task force conducted a comprehensive and systematic review of studies in this area.² The task force examined dementia over the course of PD, including its epidemiology; its effects on different a…

The risk factors for PD dementia can be grouped into clinical, molecular, and structural/functional imaging risk factors – as depicted on the slide.¹

Several potential therapies and interventions have been proposed or researched to tackle the cognitive symptoms of PD, and…
