Hepatic Encephalopathy

Hepatic Encephalopathy

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 shunting—including...

Long-term Depression

Long-term Depression

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

Mania and Antimanic Drugs: Overview

Mania 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...

Summary

A woman experienced lithium toxicity symptoms including stupor and fever. Despite renal replacement therapy, neurological deficits persisted before full recovery, highlighting the need for careful lithium level monitoring.

Psychiatry

Background:

Lithium is a common mood stabilizer for bipolar disorder.
Therapeutic lithium levels require careful monitoring to prevent toxicity.
Elderly patients or those with renal impairment are at higher risk.

Observation:

A 53-year-old female patient presented with stupor, tremors, fever, and oliguria.
Electrocardiogram revealed a widened QRS complex.
Laboratory results indicated elevated urea, creatinine, and lithium levels (8.0 mEq/L).

Findings:

The patient received renal replacement therapy to reduce plasma lithium concentrations.
Neurological symptoms, including stupor and speech impairment, persisted for several days post-dialysis.
Complete recovery was eventually achieved after several additional days.

Implications:

This case underscores the potential for severe lithium toxicity even with levels only moderately above the therapeutic range.
Persistent neurological symptoms despite prompt treatment emphasize the complex relationship between lithium levels and neurotoxicity.
Close monitoring of lithium levels and renal function is crucial, especially in patients with risk factors for impaired lithium clearance.
