Parkinson's Disease: Treatment

299
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

598
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...

Drugs for Treatment of Constipation-Predominant IBS

210
Pharmacological therapies for IBS-C are designed to alleviate abdominal discomfort and enhance bowel function. In patients with IBS-C, fiber supplements may help soften stools and decrease straining, but may also lead to increased gas production and bloating. Osmotic laxatives like milk of magnesia are frequently used to soften stools and increase stool frequency in IBS-C patients. In addition, two drugs approved for use in severe IBS-C adult cases are linaclotide (Linzess) and lubiprostone...

Neural Regulation

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.

Drugs for Treatment of Diarrhea-Predominant IBS

213
Diarrhea-predominant irritable bowel syndrome (IBS-D) is a subtype of IBS characterized primarily by frequent, loose, or watery stools, abdominal pain, and abdominal discomfort. Therapeutic approaches to managing IBS-D include dietary changes, stress management techniques, and pharmaceutical interventions.
Two specific drugs used in the treatment are alosetron (Lotronex) and eluxadoline (Viberzi). Alosetron, a 5-HT3 antagonist, works by slowing the movement of stools in the gut, reducing bowel...

Drugs Affecting GI Tract Motility: Other Laxatives

275
Laxatives are primarily used to alleviate constipation, a common gastrointestinal disorder characterized by infrequent bowel movements and difficulty passing stools. They work by various mechanisms to increase the volume or frequency of bowel movements. The primary modes of action of laxatives include increasing stool bulk, softening the stool, stimulating intestinal motility, and osmotically drawing water into the intestines.
Osmotic or saline laxatives, like magnesium hydroxide or milk of...

Summary
This summary is machine-generated.

Constipation is a common gastrointestinal issue in Parkinson's disease (PD), often appearing decades before motor symptoms. Management is complex due to PD-related patient factors, with limited evidence for current treatments.

Area of Science:

  • Neurology
  • Gastroenterology
  • Movement Disorders

Background:

  • Constipation affects over 50% of Parkinson's disease (PD) patients.
  • It is a significant prodromal symptom, potentially preceding motor deficits by decades.
  • Constipation severity parallels motor and non-motor PD progression, including cognitive decline and depression.

Purpose of the Study:

  • To review the pathophysiology and management challenges of constipation in Parkinson's disease.
  • To highlight the complexity of treating constipation in PD patients.

Main Methods:

  • Literature review on constipation in Parkinson's disease.
  • Analysis of the pathophysiology of obstructed defecation in PD.
  • Discussion of complicating patient factors and treatment limitations.

Main Results:

  • Obstructed defecation due to skeletal muscle dysfunction is the primary cause.
  • Patient factors like dysphagia, cognitive impairment, and depression complicate management.
  • Evidence supporting current constipation therapies in PD remains limited.

Conclusions:

  • Constipation is a prevalent and complex symptom in Parkinson's disease.
  • Effective management strategies for constipation in PD are needed.
  • Further research is required to establish evidence-based treatments for PD-related constipation.
