Alteraciones cognitivas en pacientes con hidrocefalia crónica del adulto (“normotensiva”). Propuesta de un protocolo para su evaluación clínica

Normal pressure hydrocephalus (NPH) is characterized by gait disturbance, urinary incontinence and dementia, and is associated with variable ventricular enlargement. The most accepted treatment of NPH is the placement of a cerebrospinal fluid shunt. Owing to the characteristics of the patients and the invasive nature of the surgical treatment, it is fundamental to detect those patients who could obtain a greater benefit from the treatment. Neuropsychological assessment of these patients could significantly contribute to a better diagnosis of NPH, determining a cognitive deterioration profile for these patients, allowing the assessment of treatment efficacy and helping to detect other additional causes of dementia. The aim of this study is to describe the cognitive deterioration profile of NPH patients and to present the clinical, functional and neuropsychological assessment protocol used in our hospital.
