[6] [15] About 3 in 100,000 people develop the disease per year. [3] The average age at diagnosis is 64, and the disease occurs more commonly in males than females. [2] [3]

The neuropathologist grades the tumor by looking for atypical cells, the growth of new blood vessels, and for indicators of cell division called mitotic figures. [citation needed]
Dysembryoplastic neuroepithelial tumour (DNT, DNET) is a type of brain tumor. Most commonly found in the temporal lobe, DNTs have been classified as benign tumours. [1] These are glioneuronal tumours comprising both glial and neuron cells and often have ties to focal cortical dysplasia. [2]
