What is Delirium in Older Adults?

Delirium presents as acute onset confusion with inattention, disorganized thinking, and altered level of consciousness, fluctuating throughout the day.

Subtypes include hyperactive (agitated), hypoactive (drowsy and withdrawn, often missed), and mixed presentations.

Diagnosis uses CAM, 4AT, or DSM-5 criteria; hypoactive delirium is frequently undiagnosed and worsens prognosis.

Delirium is associated with prolonged hospitalization, functional decline, dementia development, and increased mortality.

Symptoms

Sudden confusion and inability to focus or follow conversation
Disturbed sleep-wake cycle with night-time agitation
Visual hallucinations and persecutory delusions
Disorientation to time, place, and person
Hypoactivity with withdrawal, somnolence, and reduced oral intake
Sudden change in personality or behavior noticed by family

Risk Factors

Advanced age, dementia, and cognitive impairment
Severe acute illness, infection (especially urinary tract infection, pneumonia)
Polypharmacy, anticholinergic and benzodiazepine use
Recent surgery (especially hip fracture, cardiac surgery)
Sensory impairment (vision, hearing) and unfamiliar environment
Dehydration, electrolyte disturbance, hypoxia, and uncontrolled pain

When to See a Doctor?

If you experience any of the following symptoms, seek medical attention promptly:

  • Sudden change in mental status or new confusion at home
  • New agitation or hallucinations in a hospitalized older adult
  • Lethargy and reduced responsiveness with infection signs
  • Worsening confusion despite treatment of an underlying illness
  • Falls associated with confusion or unsteady behavior
  • Difficulty managing medications or unsafe behaviors at home

Treatment Methods

01
Identify and treat precipitants: infection, hypoxia, dehydration, drug toxicity, pain
02
Multicomponent non-pharmacological interventions (HELP protocol): orientation, mobilization, sleep hygiene, sensory aids
03
Avoid offending medications (benzodiazepines, anticholinergics, opioids when feasible)
04
Maintain hydration, nutrition, normal sleep-wake cycle, and family presence
05
Low-dose haloperidol or atypical antipsychotic only for severe agitation threatening safety
06
Post-discharge follow-up for cognitive recovery and reassessment for underlying dementia

Anaemia

Dahiliye (İç Hastalıkları)

Anaemia is a low haemoglobin level that reduces oxygen delivery, causing fatigue, pallor, and shortness of breath. It is not a disease itself but a sign of many underlying conditions. Most cases are correctable with appropriate diagnosis and treatment.

Iron Deficiency Anaemia

Dahiliye (İç Hastalıkları)

Iron deficiency anaemia develops when dietary intake, absorption, or losses create an iron shortfall, most often affecting women and children. Identifying the underlying cause is the core of management, alongside iron replacement.

Vitamin B12 Deficiency

Dahiliye (İç Hastalıkları)

Vitamin B12 deficiency can cause megaloblastic anaemia, neurological symptoms, and cognitive impairment. Early treatment with intramuscular or oral B12 largely prevents irreversible complications.

Hypertension (High Blood Pressure) Management

Dahiliye (İç Hastalıkları)

Hypertension is often called the silent killer because it progresses symptom-free for years and can damage the heart, brain, kidneys, and eyes. Regular monitoring, lifestyle change, and evidence-based drug therapy dramatically reduce cardiovascular risk.

Chronic Kidney Disease

Dahiliye (İç Hastalıkları)

Chronic kidney disease is one of the most common complications of chronic conditions such as diabetes and hypertension, and can be silent in its early stages.

Hepatitis B (HBV)

Dahiliye (İç Hastalıkları)

Hepatitis B is a DNA virus infection causing acute and chronic hepatitis with risk of cirrhosis and hepatocellular carcinoma; diagnosis integrates HBsAg, HBeAg, anti-HBc, and HBV DNA with management based on disease phase using nucleos(t)ide analogues (entecavir, tenofovir) and universal infant vaccination.

Hepatitis C (HCV)

Dahiliye (İç Hastalıkları)

Hepatitis C is an RNA virus causing chronic hepatitis that may progress to cirrhosis and hepatocellular carcinoma; modern direct-acting antiviral (DAA) pangenotypic regimens (sofosbuvir/velpatasvir, glecaprevir/pibrentasvir) achieve sustained virologic response over 95% in 8–12 weeks with universal adult screening and cure for nearly all patients.

Fatty Liver Disease

Dahiliye (İç Hastalıkları)

Non-alcoholic fatty liver disease (NAFLD) is closely related to obesity and metabolic syndrome and is largely reversible with early treatment.
