Dementias

Often defragmentation parietal-occipital alpha rhythm to 9-10 Hz. Turning to slowing of background plotting a frequency subalfa.

Firda

Firda are intermittent outbreaks of frontal delta activity in adults. They are associated with metabolic, toxic, or hypoxic encephalopathy and supratentorial, usually subcortical lesions.

Although firda is a nonspecific sign, it is highly suggestive of the early stages of a coma and is an early sign of dysfunction warning system. They are caused by interaction between the thalamus -corticales circuits. It indicates some degree of cortical alteration.
