Delirium symptoms are a sudden consciousness and cognitive disorder caused by various factors, and they are an important sign that commonly appears in older adults or patients after surgery.

Unlike simple confusion or disorientation, delirium develops acutely and is characterized by reduced concentration, impaired attention, and loss of orientation.

Today, we will take a detailed look at delirium symptoms in older adults, their causes, meaning, treatment, symptoms after treatment, diagnosis, and management methods.

The meaning of this condition, medically, refers to an acute confusional state, and it has the characteristic of being triggered over a short period with symptoms that change rapidly.

People often have difficulty maintaining concentration for long periods, and their orientation to time, place, and people gradually declines.

As a result, patients may have difficulty communicating or may become aggressive toward those around them, showing unstable behavior in daily life.

The causes of delirium vary, but in older adults, they are often associated with reduced brain reserve, infection, dehydration, electrolyte imbalance, and medication side effects.

Other common causes include hypoxia, alcohol withdrawal, and liver or kidney dysfunction, as well as physical stress such as major surgery, trauma, or prolonged hospitalization.

It is especially common in intensive care unit patients and older adults, and the more underlying conditions a person has, the higher the likelihood of developing it.

Typical delirium symptoms include impaired attention, confusion, memory decline, hallucinations, delusions, and sleep disturbances. Even if a person seems fine during the day, symptoms can worsen at night.

Delirium symptoms in older adults are even more pronounced, and speech may suddenly become less clear than usual, along with unstable behavior patterns.

In addition, they may not properly recognize the current place or time, may fail to recognize familiar people, or may not understand even simple words, making it similar to dementia.

Diagnosis is made by clinically observing the patient’s sudden decline in attention, loss of orientation, hallucinations, and so on, while also identifying underlying conditions and whether medications are being used.

It is important to identify the cause through blood tests, brain imaging, and oxygen saturation measurement, and to clearly distinguish it from other forms of dementia or psychiatric illness.

Treatment is carried out with the goal of addressing the underlying cause, correcting dehydration and electrolyte imbalance, and using antibiotics if there is an infection.

If medication is the cause, it should be discontinued or changed, and if anxiety, agitation, or aggression are severe, antipsychotics and sedatives may be used short term.

However, if delirium occurs after surgery, multifaceted management methods such as pain control, improving the sleep environment, and early rehabilitation are important.

It is advisable to maintain a quiet and bright environment, and to help the patient regain a sense of reality quickly by talking often with family members or people nearby.
