Parkinson's Disease: Treatment

940
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

1.7K
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...

Neural Regulation01:37

Neural Regulation

43.0K
Digestion begins with a cephalic phase that prepares the digestive system to receive food. When our brain processes visual or olfactory information about food, it triggers impulses in the cranial nerves innervating the salivary glands and stomach to prepare for food.

REM Sleep Behavior Disorder01:15

REM Sleep Behavior Disorder

1.3K
REM Sleep Behavior Disorder (RBD) is a sleep disorder characterized by the absence of muscle paralysis that normally occurs during the REM phase of sleep. This absence allows individuals to physically act out their dreams, which are often vivid and disturbing. Common behaviors exhibited during episodes include kicking, punching, and yelling. These actions can be dangerous, potentially leading to injuries for the person with RBD or their bed partner.
RBD is significantly associated with...

Brainstem

5.5K
The brainstem, located inferior to the brain and superior to the spinal cord, serves as a bridge between the cerebrum and the spinal cord. It plays a vital role in relaying information and controlling critical life functions. It comprises three primary regions: the midbrain, pons, and medulla oblongata.
The Midbrain
The midbrain is located beneath the diencephalon and connects the cerebrum with the lower parts of the brain. The cerebral peduncles are prominent midbrain structures that house the...

Summary

Parkinson's disease (PD) tremor significantly impacts patients, with levodopa often providing insufficient relief. Optimizing diverse therapies is key to managing this distressing and disabling symptom.

Area of Science:

  • Neurology
  • Movement Disorders

Background:

  • Tremor is a highly visible and distressing Parkinson's disease (PD) symptom.
  • Levodopa offers limited tremor control for about half of PD patients, presenting a therapeutic challenge.
  • PD tremor significantly impacts psychosocial well-being and daily functioning.

Purpose of the Study:

  • To review the challenges and current management strategies for Parkinson's disease tremor.
  • To highlight the pathophysiology and psychosocial burden associated with PD tremor.

Main Methods:

  • Literature review of tremor in Parkinson's disease.
  • Analysis of current pharmacological and non-pharmacological treatment approaches.
  • Discussion of emerging therapeutic interventions.

Main Results:

  • Nearly all individuals with PD experience tremor, though severity varies.
  • Tremor pathophysiology involves basal ganglia and cerebello-thalamo-cortical circuits.
  • Current management includes dopaminergic/nondopaminergic drugs, DBS, and MR-guided focused ultrasound.

Conclusions:

  • Refractory tremor remains a significant challenge in Parkinson's disease management.
  • Optimizing therapeutic strategies is essential to reduce the burden of PD tremor.
  • Further research into novel interventions is needed.
