Neural Regulation01:37

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.

Parkinson's Disease: Overview

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 to...

Parkinson Disease ll: Pathophysiology

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...
Parkinson's Disease: Treatment01:24

Parkinson's Disease: Treatment

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 its...
Parkinson Disease l: Introduction01:24

Parkinson Disease l: Introduction

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 which...

Area of Science:

  • Neuroimaging
  • Neurodegenerative Diseases
  • Parkinson's Disease

Background:

  • Functional imaging use in neurodegenerative diseases is growing.
  • In Parkinson's disease (PD), imaging reveals more than just dopaminergic deficits.
  • It uncovers functional network changes linked to motor and non-motor PD symptoms, like cognitive decline.

Purpose of the Study:

  • To highlight the expanding role of functional imaging in Parkinson's disease research and clinical practice.
  • To emphasize the utility of these techniques in understanding disease pathophysiology beyond traditional markers.
  • To showcase their potential in diagnosis, treatment assessment, and monitoring disease progression.

Main Methods:

  • Review of functional imaging applications in neurodegenerative diseases, specifically PD.
  • Analysis of studies examining dopaminergic and non-dopaminergic pathways.
  • Investigation of functional network alterations in relation to motor and non-motor symptoms.

Main Results:

  • Functional imaging has broadened the understanding of PD pathophysiology.
  • Alterations in functional networks are associated with both motor and non-motor symptoms, including cognitive dysfunction.
  • Imaging aids in tracking disease progression and evaluating therapeutic interventions.

Conclusions:

  • Functional imaging is crucial for advancing Parkinson's disease research.
  • These methods offer potential for early PD diagnosis and differentiation from other parkinsonian disorders.
  • Clinical applications include monitoring disease progression in research and trials.
