Summary
This study details a rare case of clonic perseveration following an acute ischemic stroke. Understanding this poststroke movement disorder offers insights into brain injury mechanisms.
Area of Science:
- Neurology
- Neuroscience
- Movement Disorders
Background:
- Poststroke movement disorders are common, encompassing conditions like parkinsonism, dystonia, and chorea.
- These disorders significantly impact patient recovery and quality of life after a stroke.
Observation:
- A patient presented with clonic perseveration, a specific type of involuntary, repetitive muscle contraction.
- This manifestation occurred two days after experiencing an acute ischemic stroke.
Findings:
- The case highlights clonic perseveration as a distinct poststroke movement disorder.
- Phenomenological description and potential pathophysiological mechanisms are discussed, contributing to the understanding of stroke-related neurological sequelae.
Implications:
- This case expands the known spectrum of movement disorders following ischemic stroke.
- Further research into the pathophysiology of clonic perseveration may reveal novel therapeutic targets for stroke rehabilitation.

01:30Peripheral Artery Disease I: Introduction
589
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...

676
The pathophysiology of Acute Coronary Syndrome [ACD] involves several key processes:The main underlying cause of ACD is atherosclerosis, a chronic inflammatory disease characterized by the buildup of lipid-laden plaques within the coronary arteries.As the atherosclerotic plaque grows in the coronary artery, it may become unstable due to the formation of a lipid-rich core and a thin fibrous cap. Inflammatory cells within the plaque, such as macrophages, secrete enzymes that degrade the...

Long-term potentiation, or LTP, is one of the ways by which synaptic plasticity—changes in the strength of chemical synapses—can occur in the brain. LTP is the process of synaptic strengthening that occurs over time between pre- and postsynaptic neuronal connections. The synaptic strengthening of LTP works in opposition to the synaptic weakening of long-term depression (LTD) and together are the main mechanisms that underlie learning and memory.

10.0K
After a fibrin clot is formed, the next step is clot retraction, a vital process facilitated by platelet contractile proteins, such as actin and myosin. These proteins pull the fibrin strands closer together and condense the clot. This action reduces the size of the clot, creating a smaller, denser structure that effectively seals off the damaged vessel. Clot retraction consolidates the clot and helps with wound healing by bringing the edges of the damaged blood vessel closer together.

Ischemic heart disease occurs when the heart's blood supply dwindles, causing an ominous lack of oxygen and nutrients. This deficiency, stemming from reduced or obstructed blood flow, spells danger, leading to heart muscle damage and dysfunction.
