Parkinson’s disease: The lesser-known symptom which lies in your bowel movements

PARKINSON'S DISEASE symptoms develop over a long period of time and could be caused by nerve damage in the brain. An unusual sign you could be at risk lies in your bowel movements.

Parkinson’s disease (PD) is characterized by the progressive loss of dopaminergic neurons in the substantia nigra. However, other non-dopaminergic neuronal systems such as the serotonergic system are also involved. Serotonergic dysfunction is associated with non-motor symptoms and complications, including anxiety, depression, dementia, and sleep disturbances. This pathology reduces patient quality of life. Interaction between the serotonergic and other neurotransmitters systems such as dopamine, noradrenaline, glutamate, and GABA controls the activity of striatal neurons and are particularly interesting for understan...

Neurorehabilitation is hampered due to social distancing and fear due to the chance of getting coronavirus disease, 2019 (COVID-19). Home-based or community-based and outpatient-based rehabilitation are restricted temporarily to protect both patients and caregivers from COVID-19 infection. Lack of physical activities during lockdown may lead to worsening of various motor and non-motor symptoms in patients with Parkinson's disease (PD) [1]. Therefore, to reduce the spread of the virus, digital rehabilitation (E-Rehabilitation) strategies should be adopted as an alternative mode to deliver rehabilitation services at the community level.

AbstractParkinson ’s disease (PD) is a neurodegenerative disorder characterized by loss of dopaminergic neurons. Dopaminergic system is interconnected with the hypothalamic–pituitary–thyroid axis. Dopamine (DA) upregulates thyrotropin releasing hormone (TRH) while downregulating thyroid stimulating hormone (TSH ) and thyroid hormones. Moreover, TRH stimulates DA release. PD is associated with impaired regulation of TSH and thyroid hormones (TH) levels, which in turn associate with severity and different subtypes of PD, while levodopa and bromocriptine treatment can interfere with hypothalamic–pituit...

This study aimed to characterize the neurophysiological correlates of gait in the human pedunculopontine nucleus (PPN) region and the globus pallidus internus (GPi) in Parkinson’s disease (PD) cohort. Though much is known about the PPN region through animal studies, there are limited physiological recordings from ambulatory humans. The PPN has recently garnered interest as a potential deep brain stimulation (DBS) target for improving gait and freezing of gait (FoG) in PD. We used bidirectional neurostimulators to record from the human PPN region and GPi in a small cohort of severely affected PD subjects with FoG desp...

Authors: Melchionda D, Varvara G, Perfetto D, Mascolo B, Avolio C Abstract Parkinson's disease (PD), which is not only a motor disease, is one of the most frequent neurodegenerative diseases and affects 1.5-2% of people worldwide. The role of its non motor-symptoms is of first importance on quality of life. Speech impairment is considered a part of motor impairment and is widespread in PD where most frequent speech impairment is Hypokinetic dysarthria, a disorder characterized by reduced articulation movements and phonetic monotony. Many PD patients show difficulty in accessing the lexicon related to cognitive impa...
