Essence of physical dependence
Withdrawal syndrome occurs as a consequence of established physical dependence. In chronic alcoholism, abrupt cessation of alcohol intake leads to a major disruption of physiological functions. The central disorder during this period is compulsive pathological craving for alcohol. The patient's emotional background is severely disturbed and can manifest in three variants:
- Guilt, depression, and doom (up to suicide attempts).
- Rage, aggression, and irritability (attempts to obtain alcohol by force are possible).
- Undefined anxiety and vulnerability, which serves as a precursor to the development of psychosis.
Clinical manifestations
The symptoms of the syndrome affect all body systems and include three main groups of disorders:
- Psychopathological disorders: total insomnia (or interrupted severe sleep with nightmares), dysphoria, fear of cardiac death, severe melancholy. Progression to alcohol-induced psychoses is possible.
- Neurological disorders: generalized tremor, nystagmus, instability in the Romberg test. In severe cases, against the background of restlessness and insomnia, epileptiform seizures occur with loss of consciousness and tongue biting.
- Somatic and autonomic manifestations: facial hyperemia and puffiness, profuse sweating on the forehead, unquenchable thirst. The cardiovascular system responds with elevated blood pressure (arterial hypertension), tachycardia, and various arrhythmias. Dyspnea, nausea, vomiting, and a complete lack of appetite are also characteristic.
Dynamics and complications
Without active correction and intensive care, a severe withdrawal syndrome is extremely dangerous. Although acute symptoms may resolve on their own by days 3–5, the risk of complications during this period is maximal. These include:
- Sudden cardiac death due to excessive stress on the heart.
- Development of acute encephalopathy (a combination of neurological deficit and psychosis).
- Sharp exacerbation of chronic diseases: pancreatitis (accompanied by girdle pain and diarrhea), gastritis, hepatitis (manifested by exhausting hiccups), coronary insufficiency, and even hemorrhoids.
Alcoholism as a systemic disease
Somatic disorders in alcoholism develop early and are inseparable from psychiatric ones. The disease is systemic in nature. Physiological disruptions directly determine the severity of the psychiatric picture:
- Liver damage (ranging from fatty degeneration to cirrhosis) significantly exacerbates encephalopathy.
- The presence of pancreatitis sharply increases the likelihood of developing delirium tremens.
- Alcoholic polyneuropathy (paresthesias, decreased foot sensitivity) is closely linked to memory disorders within the framework of Korsakoff's psychosis.
Changes in tolerance
The body's reaction to alcohol (reactivity) changes as the disease progresses. In the early stages, tolerance increases, and defense mechanisms (such as vomiting) disappear. In late stages, due to the depletion of brain and organ compensatory mechanisms, physical tolerance declines. Strong alcoholic beverages begin to cause severe intoxication with depressed consciousness. At the same time, small doses no longer bring euphoria, but they are necessary to relieve craving, which forms a pattern of frequent alcohol consumption in small portions.
Briefly: answers to topical questions
What forms of alcohol-induced psychoses can develop against the background of alcoholism?
Against the background of alcoholism, alcohol-induced psychoses can develop; the sources explicitly name: delirium, hallucinosis, paranoid state.
- Alcoholic delirium — may manifest as clouded consciousness, visual and olfactory illusions/hallucinations, and delusions of persecution and reference.
- Alcoholic hallucinosis — may be accompanied by auditory hallucinations: initially elementary/akoasms, then true verbal hallucinations; anxiety, restlessness, fear, and paranoid inclusions are also described.
- Alcoholic paranoid state — debuts against the background of severe alcohol withdrawal syndrome; acute and protracted forms are distinguished.
- Korsakoff's amnestic psychosis — described as a frequent complication of late-stage alcoholism; polyneuropathy is closely related to memory disorders within Korsakoff's psychosis.
Which groups of drugs are used for the pharmacological management of alcohol withdrawal syndrome?
For the pharmacological management of alcohol withdrawal syndrome, severe AWS, and related alcohol-induced psychoses, the sources indicate:
- GABAergic agents: benzodiazepine tranquilizers, barbiturates, zopiclone, zolpidem, sodium oxybate. Available injectable drugs include diazepam, bromdihydrochlorophenylbenzodiazepine, thiopental sodium, hexobarbital.
- Agents for managing psychomotor agitation: diazepam, haloperidol, droperidol, hexobarbital, sodium oxybate. In delirium, antipsychotics have only a symptomatic effect and are ineffective without GABAergic drugs.
- Parenteral fluids and vitamins: the basis of detoxification and management of the abstinence period.
- Furosemide: used for fluid retention during infusion therapy.
- Pyrogenal: indicated as a pyrotherapy agent for managing withdrawal in patients with alcoholism.
Stimulants and antidepressants are undesirable in the initial abstinence period; introducing them into the regimen is safe only in the second week of abstinence.
Variants of emotional disturbances in withdrawal syndrome can be conditionally divided into three directions: "aggression" (anger, irritation), "autoaggression" (guilt, helplessness, suicidal thoughts), and "panic" (anxiety, fear, anticipation of threat).
Class and exam questions
How to distinguish withdrawal syndrome from intoxication in a healthy person?
In a healthy person, alcohol poisoning causes an aversion to alcohol. In withdrawal syndrome, alcohol is perceived as the only source of salvation, and an irresistible compulsive craving for it develops.
Why is it important to check foot sensitivity during a patient examination?
This is necessary to detect alcoholic polyneuropathy. Decreased sensitivity, paresthesias, and hyperpigmentation on the legs are frequent signs of peripheral nervous system damage in alcoholism.
How long does alcohol craving persist after cessation?
Acute physical and autonomic symptoms of withdrawal usually disappear by days 3–5. However, intense pathological craving for alcohol can persist for a long time — up to one month.
