Delirium

Delirium is a medical term. The condition is also known as acute confusional state, but this term is not frequently used anymore, because it can have many different meanings. Doctors use it to describe patients who have lost parts or all of their ability to focus attention. People who suffer from it may also have problems concentrating or remembering things and people. Delirium is a medical symptom. It is not a disease. Delirium is also considered a type of confusion, but a more severe one than simple weaker confusion. Delirium can be caused by many things, like anticholinergic medications, too much alcohol, and benzodiazepine medications. Delirium can be confused with other mental conditions like schizophrenia, dementia, and psychosis, because all of these conditions have symptoms similar to delirium.

Symptoms

• Confused thinking
• Not being aware of the surroundings
• Trouble focusing on a topic or changing topics

Causes

A delirium can have many causes. The most common ones include:

• Injuries to the head or the nervous system
• Mental illness
• Trauma or shock
• Fever or pain
• Certain substances found in drugs or poisons
• Problems with metabolism. If a substance is transformed into another using an enzyme, a problem with that enzyme will lead to too much of the first, and too little of the second substance.
• Not having enough water, or food, or sleep
• Withdrawal symptoms (when people try to get away from a drugs or alcohol addiction). The delirium associated with alcohol withdrawal is called delirium tremens.
• Antihistamine medications like Promethazine, Doxylamine, Diphenhydramine, Dimenhydrinate.

Definition

There are several definitions of what constitutes a delirium, but in general, the following is true:

• Disturbance of consciousness; problems to focus, shift the focus, concentrate, or shift concentration from one item to another.
• hallucinations; reduced ability to solve problems.
• Sleeping problems are common, very often the circadian rhythm is lost.
• Problems with thinking; problems remembering things.

Treatment

Deliria are often treated with special drugs, called antipsychotics. These medications can help people feel better with their delirium. Benzodiazepines are the most commonly used medications for alcohol withdrawal. They help calm excited nervous systems. Intravenous fluids with vitamins and minerals are often used to treat dehydration or bring electrolytes back into balance.

Delirium is always a medical emergency, because it is impossible to predict how it develops. Worst-case scenarios include cardiac arrest, and malfunctions of the metabolism. In order to be able to treat delirium, its cause must be found. In the case of alcoholism, the most common cause for a delirium is the withdrawal of alcohol. This condition is known as delirium tremens.
