Parkinson's Disease: Treatment

1.4K
Neurodegenerative disorders, such as Parkinson's Disease (PD), involve the gradual and irreversible destruction of neurons in particular brain areas. These disorders exhibit standard features like proteinopathies, selective vulnerability of some neurons, and an interaction of intrinsic properties, genetics, and environmental influences in neural injury.
Parkinson's Disease is primarily a result of the loss of dopaminergic neurons in the substantia nigra pars compacta. The cornerstone of...

Parkinson's Disease: Overview

2.2K
Neurodegenerative disorders are progressive diseases that cause irreversible damage and loss to neurons in specific brain areas. Examples of these disorders include Parkinson's disease, Alzheimer's disease, Multiple Sclerosis (MS), and Amyotrophic Lateral Sclerosis (ALS). These disorders share characteristics such as proteinopathies, selective neuronal vulnerability, and a complex interplay between genetic and environmental factors. The primary therapeutic goal for these conditions is...

Parkinson Disease l: Introduction

21
Parkinson’s disease is a chronic, progressive neurodegenerative disorder that primarily affects movement. It is characterized by motor symptoms such as resting tremors, muscle rigidity, bradykinesia (slowness of movement), and postural instability. Patients may notice hand tremors at rest, stiffness during movement, or a shuffling gait. In addition to motor features, non-motor symptoms include sleep disturbances, mood and behavioral changes, constipation, and cognitive impairment, all of...

Parkinson Disease ll: Pathophysiology

22
Parkinson disease (PD) is a progressive neurodegenerative disorder primarily affecting movement, with additional non-motor features. Its pathophysiology involves complex interactions among genetic susceptibility, environmental exposures, and cellular dysfunction, including dopaminergic neuron loss, protein aggregation, and mitochondrial impairment.Selective NeurodegenerationA key feature is the degeneration of dopaminergic neurons in the substantia nigra pars compacta, leading to reduced...

Exercise and Muscle Performance01:27

Exercise and Muscle Performance

6.1K
Exercise induces a range of adaptations in muscle tissue, depending on the type and duration of activity. Such physical training can be broadly categorized into two types: endurance exercises and resistance exercises.
Endurance exercises
Endurance exercises involve running, swimming, or cycling, which require repetitive movements with low force output. When a person engages in endurance exercise, a few noticeable changes occur in their skeletal muscles. For instance, the number of capillaries...

Area of Science:

  • Neurology
  • Exercise Science
  • Rehabilitation Medicine

Background:

  • Parkinson's disease (PD) is a neurodegenerative disorder affecting motor function.
  • Previous studies, like the PRET-PD trial, indicated progressive resistance exercise (PRE) benefits motor signs in PD.
  • The long-term impact of different exercise programs on physical function in PD remains less understood.

Purpose of the Study:

  • To assess the long-term effects of PRE versus modified Fitness Counts (mFC) on physical function in individuals with PD.
  • To analyze functional outcomes at 6 and 24 months, both on and off medication.

Main Methods:

  • A secondary analysis of the PRET-PD trial data involving 38 idiopathic PD patients.
  • Participants were randomized to either PRE or mFC groups, exercising twice weekly for up to 24 months.
  • Standardized functional outcome measures were assessed at baseline, 6, and 24 months by blinded evaluators.

Main Results:

  • No significant differences in physical function measures were observed between the PRE and mFC groups at 6 or 24 months.
  • Both exercise programs led to significant improvements in most physical function measures from baseline to 24 months when tested on medication.
  • Improvements were also noted off medication, with the 6-minute walk test (6MWT) showing significance in this condition.

Conclusions:

  • Twenty-four months of supervised, structured exercise, whether PRE or mFC, effectively enhances functional performance in individuals with moderate PD.
  • Structured and supervised exercise should be integrated into the long-term care plans for Parkinson's disease patients.
  • Both exercise modalities demonstrate efficacy in maintaining and improving physical function over an extended period.
