    2. The subject must provide written (if capable) informed assent
  2. Subject requires some or complete assistance with one or more of the following:

    3. All-cause dementia, possible or probable Alzheimer's disease (AD)
    4. Frontotemporal degeneration spectrum disorders, including possible or probable:

    i. Behavioral variant frontotemporal dementia

    ii. Progressive supranuclear palsy

    iii. Corticobasal degeneration

    e. Vascular dementia, including post-stroke dementia multi-infarct dementia and/or subcortical ischemic vascular dementia (SIVD)

  4. Has a designated study partner/caregiver
  5. Can come to the clinic for study visits with a study partner/caregiver
  6. If the subject is female, she must not be pregnant or breastfeeding. She must also be of non-childbearing potential (defined as either surgically sterilized or at least 1 year postmenopausal) or must agree to use a clinically acceptable method of contraception or be abstinent.
  7. If the subject is taking an antipsychotic medication at the time of screening, the antipsychotic medication must be discontinued 2 weeks or 5 half-lives (whichever is longer)

Exclusion Criteria:

  1. Is in hospice, is receiving end-of-life palliative care, or is bedridden
  2. Has psychotic symptoms that are primarily attributable to delirium or substance abuse (i.e., neuropsychiatric symptoms not related to neurodegenerative disease)
  3. Has current evidence of an unstable neurological, cardiovascular, respiratory, gastrointestinal, renal, hepatic, hematologic, or other medical disorder, including cancer or malignancies that, in the judgment of the Investigator, would jeopardize the safe participation of the subject in the study or significantly interfere with the conduct or interpretation of the study
  4. Has a known personal or family history of long QT syndrome or family history of sudden cardiac death
  5. Has a clinical significant CNS abnormality that is most likely contributing to the dementia or findings on MRI or CT including:

    1. intracranial mass lesion
    2. vascular malformation
    3. evidence of >4 hemosiderin deposits
  6. The urine drug screen result at Visit 1 (Screening) indicates the presence of amphetamine/methamphetamine, barbiturates, cocaine, or phencyclidine (PCP). Subjects who test positive for amphetamines and who have a valid prescription may be retested if they agree to abstain from the medication for the length of their participation in the study. The presence of benzodiazepines, marijuana (THC), or opiates does not necessarily exclude the subject from the study, as assessed by the Investigator in consultation with the Medical Monitor.
  7. Has previously been enrolled in any prior clinical study with pimavanserin or is currently taking pimavanserinIs judged by the Investigator or the Medical Monitor to be inappropriate for the study for any reason

Additional inclusion/exclusion criteria apply. Patients will be evaluated at screening to ensure that all criteria for study participation are met. Patients may be excluded from the study based on these assessments (and specifically, if it is determined that their baseline health and psychiatric condition do not meet all pre-specified entry criteria).
