An ASD child's brain grows at a very rapid rate and is almost fully grown by the age of 10. [12] Recent fMRI studies have also found altered connectivity within the social brain areas due to ASD and may be related to the social impairments encountered in ASD. [16] [17]
Diffuse leptomeningeal glioneuronal tumor (DLGNT) is a rare, primary CNS tumor, classified as distinct entity in 2016 [1] and described as diffuse oligodendroglial-like leptomeningeal tumor of children in the 2016 classification of CNS neoplasms by the WHO., [2] Typically, it's considered juvenile tumors [3] but can occur in adults, [4] the average age of diagnosis is five years.

Closed-head injury is a type of traumatic brain injury in which the skull and dura mater remain intact. Closed-head injuries are the leading cause of death in children under 4 years old and the most common cause of physical disability and cognitive impairment in young people.
The cause of PBP is unknown. One form of PBP is found to occur within patients that have a CuZn-superoxide dismutase (SOD1) mutation. [7] Progressive bulbar palsy patients that have this mutation are classified with FALS patients, Familial ALS (FALS) accounts for about 5%-10% of all ALS cases and is caused by genetic factors.
Symptoms of brain injuries can also be influenced by the location of the injury and as a result, impairments are specific to the part of the brain affected. Lesion size is correlated with severity, recovery, and comprehension. [16] Brain injuries often create impairment or disability that can vary greatly in severity.
Focal cortical dysplasia (FCD) is a congenital abnormality of brain development where the neurons in an area of the brain failed to migrate in the proper formation in utero. [1] Focal means that it is limited to a focal zone in any lobe . [ 2 ]

Brain lesions associated with a clinically isolated syndrome may be indicative of several neurological diseases, like multiple sclerosis (MS) or neuromyelitis optica. In order for such a diagnosis , multiple sites in the central nervous system must present lesions, typically over multiple episodes, and for which no other diagnosis is likely.
