Subacute sclerosing panencephalitis (SSPE) is a rare, progressive neurodegenerative disorder caused by persistent aberrant measles virus infection. It is characterized by behavioral changes, cognitive decline with deterioration in academic performance, visual dysfunction, focal or generalized seizures ,myoclonus, spasticity, mutism and akinesia ultimately leading to a vegetative state. Balint's syndrome, characterized by the triad of simultagnosia, optic ataxia, and oculomotor apraxia, as an initial presenting feature of SSPE is rare.

Subacute sclerosing panencephalitis (SSPE) is a progressive and usually fatal disorder, arising from persistent measles virus infection in the brain. Exceptionally, prolonged survival has been noted. We report four such patients and also review current literature on long survival in SSPE.

Triggering receptor expressed on myeloid cells 2 (TREM2) is a cell surface receptor belonging to the TREM family that is predominantly expressed on myeloid cells such as granulocytes, monocytes, osteocytes, macrophages, and microglia. Although much of the functionality of TREM2 is not well understood at the molecular level, it is well established that TREM2 plays a significant role in the regulation of a broad definition of macrophage inflammatory responses. Dysregulation of TREM2 has been implicated in a large number of diseases including Alzheimer's disease, Nasu-Hakola disease, bone-related diseases, and atherosclerosis.

Background: Subacute sclerosing panencephalitis (SSPE) is a rare but fatal neurological syndrome resulting from persistent measles virus infection in the central nervous system. Despite the availability of a measles vaccine, SSPE continues to pose a significant health burden, and immunogenetic risk factors remain unclear. We aimed to study the role of the interleukin 12 (IL-12)/interferon-gamma (IFN-γ) axis, known for it's significance in antiviral defense, in the development of SSPE.
