What is hypoactive delirium?

Hypoactive delirium (also known as apathetic delirium or quiet delirium) is a subtype of delirium characterized by a state of reduced responsiveness to the environment. Patients with hypoactive delirium may appear withdrawn and unresponsive, with decreased psychomotor activity and decreased verbal output. They may also have difficulty concentrating and staying awake. In some cases, hypoactive delirium can be mistaken for depression or dementia, but it is important to distinguish these conditions as delirium is potentially reversible with appropriate treatment.

Symptoms of hypoactive delirium may include:

* Reduced responsiveness to the environment

* Decreased psychomotor activity

* Decreased verbal output

* Difficulty concentrating

* Difficulty staying awake

* Withdrawn behavior

* Apathy

* Indifference

* Confusion

* Disorientation

* Memory impairment

* Hallucinations

* Delusions

Hypoactive delirium can be caused by a variety of factors, including:

* Medications

* Alcohol or drug abuse

* Infections

* Metabolic disorders

* Neurological conditions

* Psychiatric conditions

Treatment for hypoactive delirium typically involves:

* Identifying and treating the underlying cause

* Providing supportive care

* Medication to manage symptoms

Prognosis for hypoactive delirium depends on the underlying cause and the severity of the delirium. With prompt treatment, most cases of hypoactive delirium resolve within a few days or weeks. However, some cases may persist for longer or progress to a more severe form of delirium.
