Parkinson's Disease: Overview01:15

Parkinson's Disease: Overview

1.7K
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

940
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...

Disorders of the Skeletal Muscle01:28

Disorders of the Skeletal Muscle

1.7K
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...

Muscle Stimulation Frequency01:22

Muscle Stimulation Frequency

4.2K
The contraction strength of muscles is regulated by motor neurons, which modulate the frequency of action potentials dispatched to the motor units based on the body's requirements. This process of varying the muscle stimulation frequency allows muscles to contract with a force that is precisely tailored to the needs of the moment, whether lifting a feather or a heavy box.
Wave summation
At low firing rates, motor neurons induce individual twitch contractions in muscle fibers. These twitches...

Muscles of the Forearm that Move the Hand and Fingers01:17

Muscles of the Forearm that Move the Hand and Fingers

2.3K
The muscles of the forearm that move the wrist, hand, and digits are numerous and diverse. They can be classified into two groups based on their location and function — the anterior and posterior compartment muscles.
Anterior Compartment
The anterior compartment muscles originate from the humerus. They primarily function as flexors and are also known as flexor muscles. They typically insert on the carpals, metacarpals, and phalanges. The superficial layer includes the flexor carpi...

REM Sleep Behavior Disorder01:15

REM Sleep Behavior Disorder

1.3K
REM Sleep Behavior Disorder (RBD) is a sleep disorder characterized by the absence of muscle paralysis that normally occurs during the REM phase of sleep. This absence allows individuals to physically act out their dreams, which are often vivid and disturbing. Common behaviors exhibited during episodes include kicking, punching, and yelling. These actions can be dangerous, potentially leading to injuries for the person with RBD or their bed partner.
RBD is significantly associated with...

Summary
This summary is machine-generated.

Functional tremor (FT) is a common movement disorder diagnosed using specific clinical and neurophysiological signs. Early diagnosis and multidisciplinary care are crucial for managing this condition, despite treatment challenges.

Area of Science:

  • Neurology
  • Neuroscience
  • Movement Disorders

Background:

  • Functional tremor (FT) is the most common functional movement disorder.
  • It is characterized by clinical signs like variability and distractibility.
  • Diagnosis is shifting towards positive
  • rule-in
  • criteria.

Purpose of the Study:

  • To review the diagnostic criteria and pathophysiology of functional tremor.
  • To discuss current and emerging management strategies.
  • To highlight challenges and suggest improvements in FT care.

Main Methods:

  • Review of clinical and electrophysiological diagnostic signs.
  • Analysis of neurophysiological underpinnings (motor co-activation, predictive processing).
  • Overview of multidisciplinary treatment approaches.

Main Results:

  • FT diagnosis relies on positive clinical and neurophysiological evidence.
  • Pathophysiology involves disrupted motor control and awareness.
  • Effective management requires a multidisciplinary approach.

Conclusions:

  • Functional tremor diagnosis is increasingly based on specific positive signs.
  • Multidisciplinary care is essential but often underutilized.
  • Improving training, access to neurophysiology, and research is vital for better outcomes.
