Even individuals with no prior history can exhibit severe confusion when faced with UTIs, dehydration, or surgical anesthesia. Always take preventative measures where possible and be on the lookout for early signs of trouble. Urinary Tract Infections UTIs are one of the common causes of confusion in the elderly; in fact, this is often the first thing doctors test for when treating an older patient that presents with confusion.

When patients suddenly become confused Hospital delirium is common and often goes unrecognized Updated: May 1, Published: May, When Mary, age 84, was hospitalized for a hip replacement, everything went well until a complication landed her in the intensive care unit ICU and she began behaving oddly.
She thought she was in a hotel, reported that a cartoon character had died in the bed next to hers, struggled at night to escape nonexistent intruders, and complained that the staff was ignoring the rats infesting her room.

During illness, hospitalization, or recovery from surgery or stroke, many people experience delirium, a rapidly developing and severe confusion accompanied by altered consciousness and an inability to focus.
Prolonged delirium is associated with poor long-term outcomes mental and physical and a higher mortality rate. Fortunately, there are ways to avoid delirium or minimize its impact.
How delirium develops Anything that interrupts normal brain function can cause delirium. Inflammation or toxic substances can interfere with brain function, for example, by disturbing the neurotransmitters that communicate between nerve cells. Though the causes of delirium are complex, one major pathway involves the neurotransmitter acetylcholine.
Many anticholinergic medications drugs that reduce the effect of acetylcholineincluding the antihistamine diphenhydramine Benadryl and incontinence medications oxybutynin Ditropan and tolterodine Detrolcan trigger delirium as a side effect. In vulnerable individuals, delirium can be induced by infection, insufficient food and drink, a trauma such as surgery or injury, uncontrolled pain, medications that most people tolerate well, or simply the unfamiliar surroundings of a hospital.
Delirium usually arises rapidly, fluctuates in severity, involves changes in consciousness and attention, and clears up within days or weeks. Recognizing hospital delirium We often think of people in a state of delirium as agitated, noisy, hallucinating, and possibly belligerent. This condition, called hyperactive delirium, occurs frequently during withdrawal from psychoactive drugs but occurs relatively rarely in people who like Mary have delirium related to illness or hospitalization.
Far more common is hypoactive delirium, in which the patient may be equally disoriented but is withdrawn, drowsy, or difficult to wake.
For example, a Vanderbilt University study found that all but two of 25 emergency room patients ages 65 and over who were diagnosed with hospital delirium out of surveyed had the hypo active type.
Some patients also fluctuate between the two states. In the Vanderbilt study, 19 of the 25 patients identified with a standard screening tool had not been diagnosed by emergency room physicians.
Of the 16 out of 25 admitted to the hospital, only one was diagnosed by a hospital physician at the time of admission. Recognizing delirium is critical to a successful outcome for older patients. When patients with delirium are transferred from the hospital to a nursing facility for rehabilitation, whether their delirium clears has a profound impact on their functional recovery.
A widely used screening tool is the Confusion Assessment Method. It prompts health professionals to look for several symptoms: Delirium is diagnosed if the symptoms fluctuate or appear suddenly and involve inattention as well as altered consciousness or trouble thinking.
What to do about delirium Delirium is a medical emergency until proven otherwise. The first step in treatment is identifying the underlying cause or causes. This may involve one or more of the following: There are no drugs specifically for delirium.
In fact, less medication is often better than more, since adverse reactions to drugs are a common cause of delirium.
Still, medications may be needed: The hospital staff can help shorten delirium by talking to patients and reorienting them reminding them where they are and the date and time.
