Summary
Acute toxic leukoencephalopathy is an uncommon cause of coma after drug overdose. Early MRI diagnosis is crucial for potential recovery in affected patients.
Area of Science:
- Neurology
- Toxicology
- Radiology
Background:
- Acute toxic leukoencephalopathy (ATLE) is a rare neurological condition.
- It is characterized by acute onset neurological deficits and white matter changes on MRI.
- ATLE is often associated with specific toxin exposures, including certain drugs.
Observation:
- This article presents two cases of ATLE with a rapid, severe onset.
- Patients presented with undifferentiated coma following drug overdose.
- Unexplained neurological symptoms in patients with a history of drug exposure were observed.
Findings:
- The presented cases suggest ATLE can have a more fulminant course than previously described.
- Magnetic resonance imaging (MRI) plays a vital role in diagnosing ATLE.
- Early MRI findings are important for predicting patient prognosis.
Implications:
- ATLE should be considered in comatose patients with a history of drug exposure.
- Prompt diagnosis via MRI may lead to better patient outcomes.
- Further research into ATLE subtypes and treatments is warranted.

Hepatic Encephalopathy
19
DefinitionHepatic encephalopathy is a reversible neurologic syndrome that results from advanced liver dysfunction or portosystemic shunting. It leads to disturbances in cognition, behavior, and motor function due to the brain’s exposure to gut-derived toxins that the liver fails to detoxify.EtiologyThis condition develops either in the setting of acute fulminant hepatitis or progressively during chronic liver disease, such as cirrhosis and portal hypertension. Portosystemic...

Encephalitis l: Introduction
5
Encephalitis is inflammation of the brain parenchyma, most often due to infections or autoimmune processes. It presents with neuropsychiatric features such as fever, altered mental status, behavioral changes, cognitive dysfunction, seizures, focal deficits, and sometimes autonomic instability. In some cases, the meninges are also involved, resulting in meningoencephalitis.Infectious CausesInfectious encephalitis is most commonly viral but can also result from bacterial, fungal, or parasitic...

Brain Abscess l: Introduction
6
A brain abscess is a focal, intracerebral infection characterized by a localized collection of pus within the brain parenchyma, resulting from microbial invasion and the body’s inflammatory response. It progresses through stages: early and late cerebritis, followed by early and late capsule formation, reflecting tissue destruction, immune response, and eventual encapsulation.Etiology and PathogenesisCausative organisms vary with source and host factors, often involving polymicrobial...

Encephalitis ll: Pathophysiology
11
Encephalitis is inflammation of the brain parenchyma caused by direct viral invasion or immune-mediated mechanisms triggered by infections or tumors. Both processes lead to neuronal injury, disrupted neurotransmission, and diverse neurological symptoms, often with overlapping clinical and pathological features.Autoimmune EncephalitisIn autoimmune encephalitis, antibodies target neuronal antigens on cell surfaces, synapses, or within neurons. A key example is anti-NMDAR encephalitis, which can...

Cerebral Edema ll: Pathophysiology
2
Vasogenic edema is a major form of cerebral edema characterized by abnormal accumulation of fluid in the brain’s extracellular space due to disruption of the blood–brain barrier (BBB). The BBB is a specialized structure composed of endothelial cells connected by tight junctions, supported by astrocytic endfeet and a basement membrane. Under normal conditions, it tightly regulates the movement of ions, proteins, and solutes between the bloodstream and brain parenchyma. When this...

Cytotoxic Edema: Pathophysiology
4
Cytotoxic edema is a form of cerebral edema characterized by intracellular swelling of neurons, astrocytes, and other glial cells. It develops when the mechanisms responsible for maintaining ionic gradients across the cell membrane become impaired. Under normal physiological conditions, the sodium–potassium ATPase actively transports sodium ions out of the cell and potassium ions into the cell, preserving osmotic balance and enabling electrical signaling. This pump requires a continuous...
