Summary
Brief summary (as posted)
This study will thus examine daily behaviour based on smartphone use and link it to the neurological and neuropsychological status as well as to neuroradiological studies that are part of the clinical routine. The study will examine behaviour changes before and after surgery, and how this change in measured behaviour with the smartphone relates to today's "gold standard", namely professional neuropsychological examination and quantification of brain damage on imaging studies (MRI). This study is a proof-of-principle study that intends to build the basis for larger future observational studies on patients with focal or diffuse brain pathologies.

Inclusion Criteria: * Consent of the patient * Age: ≥18 * Fluent language skills in German * Patient is scheduled for either maximum safe resection of a brain tumour/AVM via craniotomy or VP-shunting for hydrocephalus * Patient is capable to use a smartphone (based on the Google Android system) and uses a smartphone since at least 3 months * Preoperative smartphone-assessed day-to-day behaviour can be recorded for at least 1 week (7 days) Exclusion Criteria: * Presence of known neurologic or psychiatric disease other than brain tumour/AVM or hydrocephalus that can potentially influence the performance of a patient while using the smartphone (e.g. dementia, multiple sclerosis, bipolar disorder) * Foreseeable difficulties in follow-up due to geographic reasons (e.g. patients living abroad) * Patients enrolled in a different clinical trial according to KlinV (participation in another research project according to HFV is allowed, if this is not a burden to the patient)
