Summary
Stroke-like episodes (SLEs) are common in mitochondrial disorders (MIDs). Effective management strategies include L-arginine, coenzyme-Q, steroids, edaravone, creatine, and dichloracetate.
Area of Science:
- Neurology
- Genetics
- Biochemistry
Background:
- Stroke-like episodes (SLEs) are a significant clinical manifestation in patients with mitochondrial disorders (MIDs).
- These episodes frequently occur in MELAS syndrome and other mitochondrial conditions, affecting patients across all age groups.
- SLEs present clinically similar to ischemic stroke but differ in imaging findings and management approaches.
Purpose of the Study:
- To review recent findings on the management of stroke-like episodes (SLEs) in patients with mitochondrial disorders (MIDs).
- To differentiate SLEs from ischemic stroke and cerebral bleeding for accurate diagnosis and treatment.
- To identify effective therapeutic strategies for managing SLEs in MIDs.
Main Methods:
- Literature search of various databases for relevant studies on SLEs in MIDs.
- Analysis of clinical and neuroimaging characteristics of SLEs.
- Review of diagnostic criteria and therapeutic interventions.
Main Results:
- SLEs are a dominant feature of MIDs, particularly MELAS syndrome, and are characterized by vasogenic edema on MRI, often surpassing vascular territories.
- Diagnostic differentiation from ischemic stroke and cerebral hemorrhage is crucial.
- No causal therapy exists, but symptomatic treatments can resolve clinical manifestations.
Conclusions:
- Stroke-like episodes are a hallmark of certain mitochondrial disorders.
- Effective management strategies involve L-arginine, coenzyme-Q, steroids, edaravone, creatine-monohydrate, or dichloracetate.
- Further research into causal therapies for SLEs in MIDs is warranted.

01:15Ischemic Stroke ll: Pathophysiology
An ischemic stroke occurs when a cerebral blood vessel becomes obstructed, most often by a thrombus or embolus, interrupting the delivery of oxygen and glucose to brain tissue. Because neurons rely on continuous aerobic metabolism, energy failure begins within minutes of reduced perfusion. The region receiving the least blood flow becomes the infarct core, an area of irreversible cellular death. Surrounding this core lies the penumbra, a zone of hypoperfused but still viable tissue that is...
01:15Ischemic Stroke l: Introduction
Ischemic stroke is an acute cerebrovascular condition in which blood flow to a brain region is suddenly interrupted, leading to tissue infarction. Neurons depend on continuous oxygen and glucose supply, so even brief reductions in perfusion cause energy failure, ionic imbalance, and irreversible injury. Ischemic strokes are classified into thrombotic and embolic types based on their underlying mechanisms.Thrombotic MechanismsThrombotic stroke develops when a clot forms within a cerebral artery.
01:24Mania and Antimanic Drugs: Overview
Mania, a psychological condition characterized by elevated mood, increased energy, and reduced sleep need, is part of the bipolar disorder cycle. The exact cause of mania isn't entirely known, but it is thought to be a combination of genetic, environmental, and neurological factors. Bipolar disorder involves alternating manic and depressive episodes. Mood stabilizers like lithium, antipsychotics, and anticonvulsants help manage these episodes. Lithium carbonate is particularly effective as a...
01:46Electron Transport Chain: Complex I and II
The mitochondrial electron transport chain (ETC) is the main energy generation system in the eukaryotic cells. However, mitochondria also produce cytotoxic reactive oxygen species (ROS) due to the large electron flow during oxidative phosphorylation. While Complex I is one of the primary sources of superoxide radicals, ROS production by Complex II is uncommon and may only be observed in cancer cells with mutated complexes.

01:29Stroke: Introduction and Types
A stroke is an acute neurological event caused by the sudden disruption of cerebral blood flow, leading to rapid loss of neuronal function. Neurons depend on continuous oxygen and glucose supply, so even brief interruptions can cause irreversible injury within minutes. Strokes are classified into ischemic and hemorrhagic types.Ischemic StrokeIschemic strokes are most common and occur due to arterial occlusion, depriving brain tissue of oxygen and nutrients. This leads to energy failure, ionic...
01:26Transient Ischemic Attack l: Introduction
A transient ischemic attack (TIA) is a brief episode of neurological dysfunction caused by a temporary, focal reduction in cerebral blood flow. Although symptoms resemble those of an ischemic stroke, the interruption in perfusion is short-lived and does not cause permanent infarction. TIAs are clinically important because they often serve as early warning events for future stroke.Mechanisms of Transient Cerebral IschemiaTransient cerebral ischemia may arise through several mechanisms. One...
