Parkinson's Disease: Overview01:15

Parkinson's Disease: Overview

1.6K
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

916
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...

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.

Brainstem01:19

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...

Lysosomal Hydrolases01:22

Lysosomal Hydrolases

4.4K
Lysosomes are the site for the degradation of macromolecules and biological polymers released during membrane trafficking events such as secretory, endocytic, autophagic, and phagocytic pathways. The membrane-enclosed area of the lysosome, called the lumen, contains hydrolytic enzymes active in an acidic environment. These acid hydrolases are functional at a pH between 4.5 and 5 and are involved in cellular processes such as cell signaling, energy metabolism, restoration of the plasma membrane,...

Peripheral Artery Disease I: Introduction01:30

Peripheral Artery Disease I: Introduction

274
Peripheral artery disease (PAD) predominantly results from atherosclerosis, which involves the accumulation of fatty deposits, or plaques, within the walls of arteries. This causes them to narrow and harden, significantly reducing blood flow. PAD predominantly affects the legs, particularly the arteries supplying the thighs and calves. In rare cases, it may involve other arteries, including those in the arms.Etiology of PAD:The principal cause of PAD is atherosclerosis, which results from fatty...

Area of Science:

  • Neurology
  • Neuroscience
  • Genetics

Background:

  • Parkinson disease (PD) is the most prevalent neurodegenerative movement disorder.
  • Risk factors include advanced age, male gender, and environmental influences.
  • While most cases are idiopathic, genetic factors play a role in familial PD.

Purpose of the Study:

  • To provide a comprehensive review of Parkinson disease for neurologists.
  • To discuss the genetics, pathogenesis, clinical presentation, diagnosis, and pathology of PD.
  • To highlight the limitations of current treatments and the need for disease-modifying therapies.

Main Methods:

  • Review of existing literature on Parkinson disease.
  • Analysis of prevalence and incidence data.
  • Discussion of pathological hallmarks, including dopaminergic neuron loss and Lewy bodies.

Main Results:

  • PD affects approximately 108-257/100,000 individuals in Europe.
  • Cardinal motor symptoms include tremor, rigidity, bradykinesia, and postural instability.
  • Pathology involves loss of dopaminergic neurons and alpha-synuclein aggregation in Lewy bodies.

Conclusions:

  • Current treatments primarily manage motor symptoms of PD but do not halt disease progression.
  • Understanding genetic and pathogenic mechanisms is crucial for developing effective therapies.
  • Clinical diagnosis is key, supported by investigations to differentiate from other parkinsonian syndromes.
