Diagnosis for<unk>  can be quite difficult because it falls between two other disorders of diminished motivation, and one could easily see an extreme case of<unk>  as akinetic mutism or a lesser case of<unk>  as apathy and therefore, not treat the patient appropriately. If it were to be confused with apathy, it might lead to attempts to involve the patient with physical rehabilitation or other interventions where a source of strong motivation would be necessary to succeed but would still be absent. The best way to diagnose<unk>  is through clinical observation of the patient as well as questioning of close relatives and loved ones to give the doctor a frame of reference with which they can compare the patient's new behavior to see if there is in fact a case of diminished motivation. In recent years, imaging studies using a CT or MRI scan have been shown to be quite helpful in localizing brain lesions which have been shown to be one of the main causes of<unk> . Conditions where<unk>  may be present * Normal pressure hydrocephalus * Major depressive disorder * Persistent depressive disorder * Attention deficit hyperactivity disorder * Schizophrenia * Frontotemporal dementia * Parkinson's disease * Huntington's disease * Pick's disease * Progressive supranuclear palsy * Traumatic brain injury * Stroke Alzheimer's disease A lack of motivation has been reported in 25–50% of patients with Alzheimer's disease. While depression is also common in patients with this disease,<unk>  is not a mere symptom of depressions because more than half of the patients with Alzheimer's disease with<unk>  do not suffer from depression. Several studies have shown that<unk>  is most prevalent in cases of severe dementia which may result from reduced metabolic activity in the prefrontal regions of the brain. Patients with Alzheimer's disease and<unk>  are significantly older than patients with Alzheimer's who do not lack motivation. Going along with that, the prevalence of<unk>  increased from 14% in patients with a mild case Alzheimer's disease to 61% in patients with a severe case of Alzheimer's disease, which most likely developed over time as the patient got older.
