Parkinson's Disease: Overview01:15

Parkinson's Disease: Overview

523
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...

Disorders of the Skeletal Muscle

927
The clinical conditions affecting the skeletal muscle tissue are broadly categorized as musculoskeletal and neuromuscular disorders.
Musculoskeletal disorders
Musculoskeletal disorders involve injuries and conditions affecting the skeletal muscles and associated connective tissues. These disorders can arise from acute biomechanical stresses or chronic overuse and can occur across different age groups. Common injuries include sprains, fractures, and muscular strains, often resulting from...

Parkinson's Disease: Treatment

254
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...

Myasthenia Gravis: Overview and Treatment

1.3K
Myasthenia gravis is a neuromuscular transmission disorder characterized by weakness and increased fatigability of skeletal muscles. It is an autoimmune disease affecting approximately one in 2000 people, where antibodies against the α1 subunit of nicotinic acetylcholine receptors are produced.
These antibodies interfere with the function of the nicotinic receptors in three ways: by binding to the receptor and disrupting acetylcholine binding; by causing cross-linking of receptors which...

Gastrointestinal Motility Disorders01:20

Gastrointestinal Motility Disorders

331
Gastrointestinal or GI motility disorders are characterized by irregular gastrointestinal tract movements, disrupting food transit from the mouth to the anus. They are caused by damage or dysfunction in gut muscles or nerves. These disorders can cause symptoms such as severe constipation, diarrhea, abdominal pain, and swallowing difficulties. Disorders can affect any segment of the GI tract and range widely in severity, from common conditions like GERD to life-threatening conditions like...

Disorders of the Nervous Tissue

1.1K
Nervous tissue is a vital component of the human body's communication system, enabling us to perceive and respond to stimuli. However, like all other tissues, it is vulnerable to disorders and diseases that can significantly impact our neurological functioning.
Homeostatic Imbalances:
Alzheimer's disease manifests as a gradual decline in memory and cognitive abilities, attributed to the buildup of amyloid plaques and neurofibrillary tangles in the brain.
Parkinson's disease arises from the...

Area of Science:

  • Neurology
  • Neuroscience

Background:

  • Functional movement disorder (FMD) is a prevalent functional neurological disorder often presenting diagnostic and management challenges.
  • FMD manifests in various phenotypes, including tremor, dystonia, myoclonus, gait disturbances, and parkinsonism.

Purpose of the Study:

  • To provide a practical overview of functional movement disorder (FMD).
  • To discuss the role of the clinical encounter in patient acceptance of the FMD diagnosis.
  • To review recent neuroimaging findings relevant to FMD pathophysiology.

Main Methods:

  • Review of clinical examination techniques for suspected FMD.
  • Discussion of diagnostic testing maneuvers.
  • Examination of multidisciplinary treatment protocols (outpatient and inpatient).

Main Results:

  • A structured clinical examination and specific diagnostic maneuvers are crucial for assessing FMD.
  • Multidisciplinary treatment approaches are most effective for managing FMD.
  • Neuroimaging studies are advancing the understanding of FMD pathophysiology.

Conclusions:

  • Despite improved recognition, FMD diagnosis and management remain challenging for patients and clinicians.
  • The clinical encounter is vital for fostering patient acceptance of an FMD diagnosis.
  • Continued research, particularly in neuroimaging, is essential for elucidating FMD pathophysiology and improving care.
