4. Seizures: Brain damage may be associated with epileptic seizures and convulsions.
5. Cognitive impairment: Brain damage can cause cognitive impairment such as impaired memory, attention, concentration, orientation, and problem solving.
6. Psychiatric symptoms: OPGM may be accompanied by mental status changes such as depression, aggression, insomnia, delusions, or other psychiatric symptoms.
7. Speech and aphasic disorders: Damage to certain areas of the brain can lead to speech disorders, including aphasia (impaired ability to speak or understand speech).
8. Sensory impairment: OPGM can cause loss or alteration of sensory functions, such as loss of the sense of smell, hearing, vision, or touch.
9. Control dysfunction: Damage to brain structures that control organ functions (e.g., breathing, heart) can cause related symptoms.
10. Autonomic nervous system disorders: OPGM may be accompanied by changes in the regulation of autonomic functions such as blood pressure, body temperature, and sleep regulation.

The symptoms of OPGM can be varied and depend on many factors, including the location and extent of brain damage, the age of the patient, and the cause of the lesion.

Diffuse organic lesions of the brain (DOPGM) is a condition in which there are widespread and heterogeneous changes in the tissues and structures of the brain. These changes can be caused by a variety of reasons and are usually characterized by impaired brain function. [1], [2]

Organic lesions of the cerebral cortex

Is a form of brain damage in which the cerebral cortex, the outer layer of the brain, undergoes a variety of structural and functional changes. These changes can be caused by a variety of reasons, such as trauma, infection, tumor, cerebrovascular disorders, autoimmune diseases, or degenerative processes.

The symptoms and effects of organic cortical lesions will depend on the location and nature of the lesion. Here are some of the possible symptoms and conditions associated with organic cortical lesions:

1. Cognitive impairment: Organic damage to the cerebral cortex can lead to impairments in memory, attention, speech, problem solving, and other cognitive functions.
2. Epilepsy: Organic lesions of the cerebral cortex can cause epileptic seizures.
3. Motor impairment: Depending on the location of the brain lesion, organic cortical damage can cause paralysis, movement coordination disorders, and other motor problems.
4. Changes in behavior and personality: Organic lesions of the cerebral cortex can cause changes in mental state, including depression, aggression, apathy, and other mental disorders.
5. Sensory impairment: This may include loss of sensation as well as distortions in the perception of sensory stimuli.
6. Speech disorders and aphasia: Damage to the cerebral cortex can lead to speech disorders like Broca's aphasia (impaired pronunciation of words) or Wernicke's aphasia (impaired speech comprehension).

Diagnosis of organic lesions of the cerebral cortex may require various instrumental studies such as magnetic resonance imaging (MRI), computed tomography (CT), electroencephalography (EEG) and others. [3]

Organic brain damage in children

It is a condition in which the structures and functions of a child's brain undergo changes or damage that can be caused by a variety of reasons. This condition can have various consequences and can affect the physical, cognitive and emotional development of the child. Some of the major causes of organic brain damage in children are listed below:

1. Perinatal problems: Some babies may be born with organic brain damage caused by abnormal processes during pregnancy, labor, or after birth. Examples include birth asphyxia (lack of oxygen), premature birth, infections of the mother during pregnancy, and other factors.
2. Trauma: Head injuries, such as concussions or head injuries, can lead to organic brain damage in children.
3. Infections: Some infections, such as viral encephalitis or meningitis, can damage the brain and cause organic changes.
4. Congenital Anomalies: Children may be born with congenital brain abnormalities such as hydrocephalus (excess fluid buildup in the brain), vascular anomalies, or neural tube defects.
5. Vascular disorders: Vascular problems, such as strokes or brain hemorrhages, can cause organic brain damage in children.
6. Neurodegenerative Diseases: Although neurodegenerative diseases are more likely to begin in adulthood, some can begin in childhood and cause organic brain changes.

The symptoms and effects of organic brain damage in children can vary depending on the cause and degree of brain damage. They may include developmental delays, motor impairments, epileptic seizures, cognitive problems, autism, speech disorders and many other symptoms.

Treatment and care of children with organic brain lesions usually require an individualized approach and drug therapy, physical and speech rehabilitation, and psychological support. It is important to see a doctor and start treatment in time to minimize complications and help the child's development.

Stages

Degrees of organic brain damage can be classified according to the severity and extent of changes in the brain. However, there is no standardized and universal classification system for grades of organic brain damage, such as in the case of burns or brain injury. The degree of brain damage is usually assessed on the basis of clinical and instrumental data and may vary from case to case.

In general, the following possible degrees of severity of organic brain damage can be distinguished:

1. Mild degree: In this case, the changes in the brain may be minor and may not be accompanied by serious symptoms. The patient may experience mild cognitive impairment or motor problems, but these may be minimal.
2. Moderate: Brain damage is more noticeable and symptoms become more severe. Cognitive, motor and emotional impairment may be moderate, limiting the patient's ability to perform everyday tasks.
3. Severe: In this case, the brain damage is severe and may be accompanied by significant brain dysfunction. Patients may lose independence and require constant care and medical support.

The degree of organic brain damage may also depend on the cause of the lesion, its location and the effectiveness of treatment. It is important to note that in each individual case, the assessment of the extent of the lesion should be made by a physician based on clinical and diagnostic findings in order to develop the most appropriate treatment and rehabilitation plan.
