Symptoms of Delirium Tremens
Delirium tremens presents with a constellation of severe autonomic hyperactivity (tachycardia, hypertension, profuse sweating, fever), altered mental status with disorientation, tremor, and visual hallucinations, typically peaking 3-5 days after abrupt alcohol cessation. 1
Core Neuropsychiatric Symptoms
Altered Mental Status and Cognitive Disturbance:
- Clouded consciousness with fluctuating symptoms that worsen at night 1, 2
- Disorientation to person, place, and time 1
- Confusion ranging from mild agitation to stupor or coma 1
- Impaired attention and awareness with disorganized thought processes 3
Perceptual Disturbances:
- Visual hallucinations are particularly common and characteristic 1, 4
- Tactile hallucinations may occur 5
- Misperceptions and illusions 1
- Transient delusions 3
Autonomic Hyperactivity
Cardiovascular and Thermoregulatory Signs:
- Tachycardia (rapid heart rate) 1, 2
- Hypertension (elevated blood pressure) 1, 2
- High fever/hyperthermia 1
- Profuse sweating (diaphoresis) 1, 2
Motor and Neurological Features
Movement Abnormalities:
- Hand tremor (characteristic feature) 1, 2
- Seizures (alcohol withdrawal seizures may precede or accompany DT) 1
- Asterixis, myoclonus, and frontal release signs 3
- Hyperreflexia 5
Behavioral and Emotional Symptoms
Psychomotor and Affective Changes:
- Agitation and restlessness 4
- Inappropriate or unsafe behavior 1
- Emotional lability 1
- Anxiety and irritability 3, 5
Associated Physical Symptoms
Gastrointestinal and Sleep Disturbances:
- Nausea and vomiting 1, 5
- Disturbed sleep-wake cycle with circadian rhythm disruption 1
- Symptoms fluctuate throughout the day, typically worsening at night 3, 1
Temporal Pattern
Critical Timing:
- Symptoms begin 6-24 hours after alcohol cessation with early withdrawal features 5
- DT typically manifests 48-72 hours after the last drink 5, 6
- Peak severity occurs at 3-5 days post-cessation 1, 5
- Duration typically lasts 5-10 days if adequately treated 6
Life-Threatening Complications to Monitor
Critical Comorbidities:
- Dehydration and electrolyte imbalances 1
- Renal failure 1
- Infection (urinary tract infections, pneumonia, sepsis) 1, 5
- Gastrointestinal bleeding 1
- Pancreatitis 1
- Liver failure 1
- Head trauma 1
- Malignant arrhythmias and respiratory arrest 2
Clinical Pitfall
The hypoactive presentation of delirium is frequently missed, leading to delayed recognition and treatment. 3 DT carries mortality rates up to 15% when untreated, with death resulting from sepsis, arrhythmias, respiratory arrest, or severe electrolyte disturbances. 5, 2 Each day of delirium duration increases mortality risk by 10%. 5
