Parkinson's Disease: Overview

487
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's Disease: Treatment

231
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...

Summary

Functional movement disorders (FMDs) are often overlooked in deep brain stimulation (DBS) patients. Prompt diagnosis of FMDs is crucial for surgical outcomes and requires further research into risk factors and patient management.

Area of Science:

  • Neurology
  • Neurosurgery

Background:

  • Functional movement disorders (FMDs) can complicate deep brain stimulation (DBS) treatment.
  • Patients undergoing DBS may present with or develop FMDs, impacting surgical decisions and outcomes.

Purpose of the Study:

  • To explore the complex relationship between FMDs and DBS.
  • To highlight the diagnostic challenges and implications of FMDs in DBS candidates and recipients.

Main Methods:

  • This study is a narrative review.
  • It synthesizes current understanding of FMDs in the context of DBS.

Main Results:

  • Unrecognized FMDs in DBS candidates often manifest as functional dystonia.
  • FMDs developing after DBS typically present as functional tremor.
  • Comorbid FMDs present significant challenges for surgical candidacy and management.

Conclusions:

  • FMDs in DBS patients are frequently underdiagnosed and critically impact surgical success.
  • Further investigation into risk factors for post-DBS FMDs and optimal management strategies for comorbid cases is essential.
