Parkinson's Disease: Treatment

240
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

501
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...

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.

Area of Science:

  • Neuroscience
  • Biochemistry
  • Pathology

Background:

  • Essential trace elements are vital for neuronal function.
  • Dysregulation of trace elements is increasingly linked to neurodegenerative disorders, especially Parkinson's disease (PD).

Purpose of the Study:

  • To systematically review recent evidence on essential trace elements (iron, zinc, copper, manganese, selenium) in PD pathogenesis.
  • To explore these elements as potential therapeutic targets for PD.

Main Methods:

  • Comprehensive literature search (Jan 2023 - Dec 2024).
  • Screening of 1231 studies, with 63 meeting PRISMA guidelines.
  • Methodological assessment using PEDro scale and AMSTAR-2 checklist.
  • Selection of 18 high-quality studies using diverse research models.

Main Results:

  • Iron accumulation in substantia nigra observed in PD.
  • Zinc shows dual roles in oxidative stress and autophagy.
  • Copper contributes to alpha-synuclein aggregation.
  • Selenium exhibits neuroprotective effects via antioxidant pathways.
  • Manganese linked to mitochondrial dysfunction and neuroinflammation.

Conclusions:

  • Trace element imbalances contribute to PD pathology through redox imbalance, protein misfolding, and impaired homeostasis.
  • These elements show potential as biomarkers and therapeutic targets for PD.
  • Personalized, metal-based interventions warrant further investigation for PD treatment.
