Auditory hallucinations are experiences in which a person hears sounds, speech, or noises that do not actually exist in the environment.

Attention deficit hyperactivity disorder

The terms "attention deficit hyperactivity disorder" and "developmental disorders" describe a clinical phenomenon rather than being the name of independent diseases. Much effort has been made to identify within these conditions separate nosological units with specific etiology and pathogenesis.

Atropine poisoning

Atropine is widely used in medicine on its own in the form of sulfate and is part of many complex drugs - anti-asthmatic (Solutan, Franol), antispasmodics (Besalol, Spazmoveralgin) and some others. It is used in ophthalmology and psychiatry.

Atrophy of the skin striated. Causes. Symptoms. Diagnosis. Treatment

Stripe atrophy of the skin (syn. stripe atrophoderma) is a peculiar skin atrophy in the form of narrow, wavy, sunken stripes. The etiology and pathogenesis have not been established.

Atrophy of the optic nerve. Causes. Symptoms. Diagnosis. Treatment

Clinically, optic nerve atrophy is a combination of symptoms: visual impairment (decreased visual acuity and development of visual field defects) and pallor of the optic nerve head.

Atrophy of the gastric mucosa

Atrophy of the gastric mucosa (in medical literature – atrophic gastritis) is a type of chronic gastritis, manifested in progressive pathological changes in the gastric mucosa and the death of the glands that produce gastric juice.

Atrophy of gyrate.

Lobular atrophy of the choroid (gyrate atrophy) is a disease inherited in an autosomal recessive manner, with a characteristic clinical picture of atrophy of the choroid and pigment epithelium.

Atrophoderma verruciformis

Atrophoderma vermiformis (syn.: vermiform acne, symmetrical reticular atrophoderma of the face, reticular cicatricial erythematous folliculitis, etc.). Etiology and pathogenesis are unknown.

Atrophic gastritis

Autoimmune metaplastic atrophic gastritis is a hereditary autoimmune disease that is based on damage to parietal cells, leading to hypochlorhydria and decreased production of intrinsic factor.

Atrioventricular block: causes, symptoms, diagnosis, treatment

Atrioventricular block is a partial or complete cessation of impulse conduction from the atria to the ventricles. The most common cause is idiopathic fibrosis and sclerosis of the conduction system.

Atrial septal defect. Symptoms. Diagnosis. Treatment

An atrial septal defect is one or more holes in the atrial septum that allow blood to flow from left to right, causing pulmonary hypertension and heart failure. Symptoms and signs include exercise intolerance, shortness of breath, weakness, and atrial arrhythmia.

Atrial fibrillation (atrial fibrillation)

Atrial fibrillation (AF) is a rapid, irregular heart rhythm. Symptoms include palpitations, sometimes weakness, shortness of breath, and near-syncope. Blood clots often form in the atria, creating a high risk of ischemic stroke.

Atrial fibrillation

Currently, a distinction is made between brady- and tachystolic forms of atrial fibrillation. Due to its lesser effect on hemodynamics, the bradystolic form of atrial fibrillation has a more favorable course. Clinically, the tachystolic form can manifest itself as right- and left-ventricular failure. On the electrocardiogram, the RR intervals are different, and there are no P waves.

Atresia and narrowing of the nasal passages. Causes. Symptoms. Diagnosis. Treatment

Atresia and narrowing of the nasal passages can be congenital or acquired. In the latter case, they can be caused by inflammatory-purulent diseases of a non-specific and specific nature, ending in a scarring process with the formation of synechia or total cicatricial membranes, completely excluding one or both halves of the nose from the respiratory process.

Atopic dermatitis

Atopic dermatitis is a chronic allergic disease that develops in individuals with a genetic predisposition to atopy, has a relapsing course with age-related features of clinical manifestations and is characterized by exudative and/or lichenoid rashes, increased levels of serum IgE and hypersensitivity to specific (allergic) and non-specific irritants.

Atopic dermatitis

Atopic dermatitis is an acute, subacute or chronic recurrent inflammation of the epidermis and dermis, characterized by severe itching, and has a certain age-related dynamics.

Atopic cheilitis

Atopic cheilitis is a polyetiological disease, where, along with heredity, environmental risk factors play a major role. Exogenous risk factors contribute to the development of exacerbations and chronic course of the disease.

Atopic and allergic conditions: causes, symptoms, diagnosis, treatment

Type I hypersensitivity reactions include atonic and many allergic disorders.

Atony and paralysis of the esophagus. Causes. Symptoms. Diagnosis. Treatment

Atony and paralysis of the esophagus are conditions characterized by functional disorders of the neuromuscular apparatus of the esophagus, the causes of which are so numerous that they cannot be subject to any kind of comprehensive systematization.

Athletic heart: causes, symptoms, diagnosis, treatment

Athlete's heart is a set of structural and functional changes that occur in the heart of people who train for more than 1 hour almost every day. The condition does not cause subjective complaints.
