Developing a New EEG Method for the Early Diagnosis of Dementia

This is a non-invasive study investigating whether EEG, which is used in routine clinical care can be useful in diagnosing dementia. Novel in house developed software will analyse EEG data for this purpose from people with Alzheimer's disease and healthy volunteers.

Inclusion Criteria: • Clinical diagnosis of possible or probable AD (according to revised diagnostic criteria (McKhann et al., 2011, Dubois et al., 2007) Exclusion Criteria: * Significant vascular change on neuro-imaging (Fazekas grading of white matter change \>2) (Fazekas et al., 2002). * Clinical history of stroke, Parkinsonism, epilepsy or other neurological disorder. (e.g. severe auditory, visual, language or motor impairment) * Moderate to severe dementia (defined by research team but we wouldn't expect those with a mini mental state exam \[MMSE\] ≤ 18 to be able to participate) * Severe current mental health disorder (depression, psychosis). * Patients on sedating or antiepileptic medication
