Sudden, reduced blood supply to the brain causes mild or extensive brain damage, leading to a medical condition known as hypoxic-ischemic encephalopathy. This condition is also known as global hypoxic-ischemic injury or cerebral hypoxia, in older children and adults. The condition may occur in neonates before the onset of labour, during the actual delivery, or after delivery. Extensive brain damage in neonates may cause abnormal levels of consciousness, muscular tone, reflexes, feeding and respiration; as well as convulsions. The presentation of symptoms is different according to the age group affected. Drowning and asphyxiation are common causes of cerebral hypoxia in older children. In adults, cardiac arrest or cardiovascular diseases cause brain damage due to secondary hypoxia.

This condition can be classified - depending upon the severity -- as diffuse, focal, global, and massive. The reduction or cessation of oxygen to the brain causes the death of the brain cells within a few minutes. Depending upon the severity, symptoms can be temporary, long-term or permanent, leading to motor and sensory disability, paralysis, and even death. The management of this condition in the modern system of medicine is mainly supportive and depends on neurological disability and organ dysfunction. Conservative management includes the supply of oxygen, inducing hypothermia (in neonates), removing the known causes, and giving supportive intensive care treatment.

Irrespective of age and projected severity, hypoxic-ischemic encephalopathy needs to be treated on an emergency footing and calls for immediate intensive care to prevent long-term disability and permanent brain damage, as well as saving a life. This treatment is highly specialized and can only be done in modern hospitals with advanced intensive care facilities. Long-term management includes regular assessment, physiotherapy, and occupational therapy.

Ayurvedic treatment can be utilised in the management of hypoxic-ischemic encephalopathy, once the critical stage has passed, and there is a need to assess and treat long-term disability, complications and organ damage. The overall treatment needs to be decided after a complete assessment of the residual damage and disability. Ayurvedic herbal medicines which have a specific action on the central nervous system and the brain cells form the mainstay of treatment in the management of this condition. These medicines need to be given for prolonged periods and in high doses to strengthen the nerve cells in the brain as well as the central nervous system, and reduce or reverse brain damage to the maximum extent possible. This treatment can also bring about improvement at the neuromuscular junction levels and improve muscle strength, tone and coordination.

Besides, herbal medicines which can be utilised to treat cardiovascular disease and inflammation, and reduce blockage in arteries and capillaries, are also very useful in the management of this condition. Oral treatment can be supplemented with localised therapy in the form of generalised massage using medicated oils and pastes, followed by steam fomentation using medicated decoctions. Special procedures like Shirodhara and Shiro-Basti are also very useful in the management of the long-term disability resulting from hypoxic-ischemic encephalopathy.

They're also a medicine available for brain hypoxia and ischemia which name is Raw Semax powder. Raw Semax powder regulates the expression and the activation of the hippocampal (brain-derived neurotrophic factor) BDNF/(tropomyosin receptor kinase B) trkB system. It enhances selective attention at the time of information reception, increases memory consolidation and stimulates learning abilities. Raw Semax powder is an active element of Raw Semax powder drugs, which is used for the treatment of brain hypoxia and ischemia. It stimulates the activity of choline acetyltransferase. Raw Semax powder exhibits properties of the melanocortin (MC) receptor, antagonist.
