Final answer:
Alcohol withdrawal symptoms typically include tremors, hallucinations, and seizures, but not a decreased heart rate, as withdrawal often causes increases in heart rate and other symptoms of nervous system arousal.
Step-by-step explanation:
Alcohol withdrawal symptoms can include a wide range of physical and psychological effects due to the cessation of alcohol use after a period of heavy and prolonged drinking. While symptoms such as tremors, hallucinations, and seizures are associated with alcohol withdrawal, a decreased heart rate is not typically a symptom of alcohol withdrawal. Instead, individuals may experience increased heart rate, agitation, anxiety, sleep problems, and other symptoms that reflect the nervous system rebounding from the depressant effects of alcohol.
