Rapid diagnosis is important to attempt to prevent further damage to the brain and further neurologic deficits. It is a diagnosis of exclusion, so a full work up for other possible etiologies (hepatic, uremic, infectious, oncologic) should be performed. In addition to the neurological examination, diagnostic<unk> sting could include MRI, PET or SPECT brain imaging, EEG, QEEG and most importantly, neuropsychological<unk> sting. Screening for heavy metals, as well as other<unk> s, should be done immediately as those are some of the most common causes and the patient can then remove themselves from the dangerous environment. In addition, a full examination of blood (CBC) and metabolites (CMP) should be done.
