This is a sort of question, which even the best of neurologists or neurosurgeons cannot answer for sure. There are cases where an individual suffers from a mild traumatic brain injury, gets better and is discharged from the hospital within a few hours, and carries on with normal activities of daily living only to find some months later that there has been some change in his or her cognitive and executive functioning.
While mild and moderate Traumatic Brain Injury does not cause any permanent dysfunction of the brain, individuals with severe form of Traumatic Brain Injury are left with certain permanent disabilities even if they are able to make it. Their prognosis remains guarded and they require assistance for certain activities of daily living throughout their life after the severe Traumatic Brain Injury.
The relation between hyperammonemia and cerebral dysfunction seems to be clear in patients with acute liver failure in which plasma ammonia have a direct correlation with the presence of intracranial hypertension and brain death. Read on to know more.
The symptoms associated with concussion can last anywhere from a few days to a couple of months. The duration of the condition depends on the severity of the brain injury involved. Grade 3 Concussion is associated with loss of consciousness that lasts for less than a minute. Grade 4 Concussion is associated with loss of consciousness which lasts for longer than a minute.
Reye’s syndrome remains a puzzle and further research is a great challenge to clinicians. The recent instruction by the Committee on Safety of Medicines, UK stated that aspirin should not be prescribed to children under the age 16 unless if it is Kawasaki disease or any prevention of blood clot formation.
Feeling off-balance when walking is not a medical condition in itself, but is a medical symptom that indicates presence of other medical condition.

Other symptoms that accompany this sensation of feeling off balance when walking can give clue about the underlying medical condition.
The episodes of BPPV are often recurrent which lasts for few minutes. BPPV without treatment may last for about a week. However, there is always a chance of reoccurrence in future. BPPV often improves by itself without any treatment. However, in advanced cases, medications may be necessary. A few home treatments are often recommended for management of the symptoms and for reducing the sensation of whirling or spinning.
Neurocognitive disorders are conditions that lead to impairment of the cognitive functions.

Know the causes, symptoms, types, treatment, lifestyle changes and prevalence of neurocognitive disorders.
The fundamental cause for the development of Athetoid Cerebral Palsy is damage to the vital structures of the brain during the development stages. This damage is either done in the basal ganglia or in the cerebellum, or both. Risk factors are premature birth, infantile jaundice, and in some cases even blood clotting within the placenta of the mother may also result in increasing the risk of a child developing Athetoid Cerebral Palsy.
The Hippocampus is important for the formation of new autobiographical and fact memories. This organ may function as a memory “gateway”, through which new memories must pass before entering the permanent storage in the brain. Damaged Hippocampus can cause loss of memory and difficulty in establishing new memories. One symptom of damage to the Hippocampus is Amnesia, or the loss of some portion of the memory. Apart from this, a damage to the Hippocampus can also cause poor impulse control, hyperactivity, and difficulty with spatial navigation or memory.
There is a reduction of fear and aggression in the person if the amygdala gets damaged. However, there is also something more to it. Bilateral lesion of amygdala also causes the affected person to have an impaired ability to interpret emotional aspect of facial expression. A damage to the amygdala is linked to autism. Amygdala has a potential relationship with the social ability of a human being, although more studies on this is required.
In cases where a cause for CSF Leak cannot be established then surgery is required to fix the spinal fluid leak. The surgery can be done through two approaches of which one is through the brain and the other is through the sinuses. The much preferred sinus approach towards fixing spinal fluid leak requires preoperative images to identify the exact location of the defect.
