Alterations in Blood Pressure01:30

Alterations in Blood Pressure

1.9K
Alterations in blood pressure, such as hypertension (high blood pressure) and hypotension (low blood pressure), significantly affect human health. Understanding these conditions' classifications, causes, and symptoms is essential for effective management and treatment.
Hypertension (High blood pressure)
Hypertension occurs when blood pressure readings consistently exceed the normal range. It is diagnosed when systolic blood pressure (the top number, indicating pressure while the heart...

Skeletal Muscle Relaxants: Adverse Effects

761
Skeletal muscle relaxants are widely used for muscle paralysis and relieving pain following any muscle injury or stiffness. However, depending on the drug type, they can have adverse effects that range from mild to severe. Usually, nondepolarizing neuromuscular blockers have minimal side effects. For example, drugs like d-tubocurarine, cisatracurium, and rocuronium cause hypotension, whereas drugs like baclofen, when stopped abruptly, can lead to the recurrence of spastic conditions.

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...

Decreased pulse rate01:14

Decreased pulse rate

824
Bradycardia is a medical condition in which the heart rate is slower than normal. It occurs when the heart's natural pacemaker, the sinus node, generates slower electrical impulses than the standard rhythm. In adults, bradycardia is diagnosed when the pulse rate falls below 60 beats per minute, indicating a deviation from the normal heart rate range.
There are specific risk factors that can elevate the likelihood of developing bradycardia. Advanced age is a significant factor, with...

Equilibrium and Balance01:15

Equilibrium and Balance

6.2K
The inner ear assumes dual functionalities of auditory perception and equilibrium maintenance. The vestibule is the organ responsible for balance. This organ contains mechanoreceptors, specifically hair cells, endowed with stereocilia, which aid in deciphering information regarding the position and motion of our heads. Two intrinsic components, the utricle and saccule, help perceive head position, while the semicircular canals track head movement. Neurological messages initiated in the...

Parkinson's Disease: Treatment01:24

Parkinson's Disease: Treatment

945
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...

Area of Science:

  • Neurology
  • Movement Disorders

Background:

  • Orthostatic tremor (OT) is a rare neurological condition characterized by high-frequency tremor during standing.
  • It can be an isolated disorder or occur with other conditions (OT Plus), like essential tremor or parkinsonism.

Purpose of the Study:

  • To summarize the current understanding of orthostatic tremor's pathophysiology.
  • To review the treatment challenges and options for orthostatic tremor.

Main Methods:

  • Literature review of studies on orthostatic tremor.
  • Analysis of proposed pathophysiological mechanisms and treatment outcomes.

Main Results:

  • The pathophysiology of OT is complex, involving a network of spinocerebellar, cerebellar, and cortical pathways.
  • Pharmacological treatments include gabapentin, clonazepam, perampanel, and levodopa.
  • Invasive treatments like spinal cord stimulation and deep brain stimulation offer modest benefits for severe cases.

Conclusions:

  • Orthostatic tremor is a network disorder with an elusive central oscillator.
  • Treatment remains challenging, with pharmacological and invasive options providing limited but potentially helpful outcomes.
