Brainscreen would reside on portable or desktop computing hardware systems within healthcare clinics and be utilized as a further advanced tool, healthcare workers may utilize, for the overall assessment and diagnosis of patients/clients. Brainscreen’s tests are based on empirically sound research. Brainscreen administrators would obtain real-time data results as to a patient’s cognitive functioning secondary to a host of possible aetiologies, such as dementia, substance abuse (or dependence), post concussive syndrome, medical illness, psychiatric disorder. Outcome results would direct healthcare workers to the next steps to be undertaken.
