Understanding HE & mHE
Hepatic Encephalopathy (HE) is a brain condition caused by liver problems (like cirrhosis, hepatitis, or liver failure). When the liver isn’t working well—like in cirrhosis—it can’t clean toxins from the blood the way it should. These toxins, especially ammonia, travel to the brain and begin to affect how it functions, disrupting its normal activity.
HE is not a mental illness, but it can cause mental and behavioral changes, some of which may be serious.
How Serious is Hepatic Encephalopathy?
HE can range from mild, barely noticeable changes to severe conditions like coma and can be life-threatening if not treated. It can develop suddenly or gradually over time.
Grade 0 of mHE: The Invisible Threat
We've all heard about the vital connection between the liver and the brain, how these two powerhouses constantly communicate to keep our bodies functioning smoothly. But what happens when that communication gets subtly disrupted, often without obvious signs? This is where Minimal Hepatic Encephalopathy (mHE) comes into play – an "invisible threat" that can significantly impact a person's life.
What is Minimal Hepatic Encephalopathy (mHE)?
Minimal Hepatic Encephalopathy (mHE) is the earliest and often most subtle stage of brain dysfunction caused by liver disease. Think back to our analogy of the liver as a waste treatment plant. In mHE, the plant isn't completely broken down, but it's not working at its optimal best. This means that small amounts of toxins, like ammonia and other neurotoxic substances, are not being efficiently filtered out of the blood and can reach the brain.

Covert HE vs. Overt HE
The crucial difference between mHE and overt Hepatic Encephalopathy (HE) is the visibility of the symptoms.
Covert HE- Under Cover
Has mHE (Grade 0) & Grade 1
mHE, is subtle and often goes unnoticed by both the patient and their loved ones. The individual might seem "just a bit off" or experience difficulties that are easily attributed to stress, fatigue, or aging.
Likely to get missed or overlooked in day to day life but if caught can has significant impact on Quality & Longevity of Life of Patient
Overt- Obvious HE
has Grade 2,3 & 4 - Visible Sign & Symptoms
Overt HE is what most people picture when they think of liver-related brain issues. It presents with clear and noticeable symptoms like significant confusion, disorientation, slurred speech, tremors, extreme drowsiness, and even coma.
It's a crisis that demands immediate attention and has usually poor prognosis in terms of Quality & Longevity of Life.
More DetailsThe Whispers of mHE that are easy to dismiss:
Early Signs
- Mild Confusion: Difficulty following complex instructions or conversations, feeling mentally foggy.
- Forgetfulness: Trouble remembering recent events, names, or appointments.
- Difficulty Concentrating: Finding it hard to focus on tasks, easily distracted.
- Subtle Personality Changes: Increased irritability, mild anxiety, or a slight withdrawal from social activities.
- Sleep Disturbances: Changes in sleep patterns, feeling excessively tired during the day or restless at night.
- Impaired Motor Skills: Subtle clumsiness, slower reaction times (which can be particularly concerning for driving or operating machinery).
