This chapter examines the status James Parkinson accorded "nonmotor" features of the malady set out in his 1817 Essay. In reading the Essay through the lens of this recently developed dichotomy I use "nonmotor" to mean the application of a late 20th-century category to a 200 year old account, whereas nonmotor designates application of the concept to contemporary understanding. While Parkinson granted "motor" components of the malady high definitional visibility, the Essay shows he was also attentive to patients' overall well-being and noticed some "nonmotor" aspects of the malady, in particular, constipation, interrupted speech, and difficulties with saliva and swallowing. He appears to have granted these features more than incidental status, especially in assessing variant pictures of the Shaking Palsy.

Background: Parkinson's disease (PD) is characterized by motor and non-motor features. There are several proposed clinical markers to define disease severity. However, if rapid eye movement sleep behavior disorder (RBD) is associated with worse prognosis of both motor and non-motor findings in PD is unknown.

Introduction: In the advanced stages of Parkinson's disease (PD), when standard drug adjustments fail to sufficiently improve patients' quality of life, device-aided therapies (DATs) such as deep brain stimulation (DBS), continuous subcutaneous apomorphine infusion (CSAI), levodopa-carbidopa intestinal gel infusion (LCIG), levodopa-carbidopa-entacapone intestinal gel infusion, or continuous subcutaneous foslevodoa-foscarbidopa infusion are beneficial in the long run. However, sometimes patients need to switch or combine DATs due to either adverse events or loss of efficacy.
Aim Of Study: The aim of this article was to summarise the existing data on the long-term efficacy and adverse events of DATs, and to review the data on the rationale and efficacy for switching or combining DATs in advanced PD.

Parkinson's disease (PD) is a prevalent neurodegenerative disorder characterized by the degeneration of dopamine neurons in the substantia nigra pars compacta, leading to motor and non-motor symptoms. While motor symptoms such as rigidity, tremor, bradykinesia/akinesia, and postural instability are well-recognized, non-motor symptoms including cognitive decline, depression, and anxiety also significantly impact patients' quality of life. Preclinical research utilizing animal models has been instrumental in understanding PD pathophysiology and exploring therapeutic interventions.

Amyotrophic Lateral Sclerosis(ALS) has traditionally been managed as a neuromuscular disorder. However, recent evidence suggests involvement of non-motor domains. This study aims to evaluate the impact of APOE and MAPT genotypes on the cognitive features of ALS.

Purpose: The outcomes of motor and non-motor features of Parkinson's disease (PD) following DBS vary among its subtypes. We tested whether pre-operative motor subtyping using the modified Tremor/PIGD ratio, could indicate the short-term motor, non-motor and quality of life (QOL) outcomes of STN-DBS.
Method: In this prospective study, 39 consecutive STN-DBS cases were assessed in Drug-OFF state before surgery and subtyped using the ratio of tremor and PIGD scores (T/P ratio).
