Title: Long Term Safety and Efficacy of Galantamine in Alzheimer's Disease (Extension INT-8)
Brief Summary: The long-term safety and efficacy of galantamine (12 mg bid) will be documented during a one year open-label treatment in subjects with Alzheimer's Disease who completed the GAL-INT-8 trial (up to 400 eligible patients). Safety will be tracked by means of adverse event reports, laboratory parameters and physical exam. Long-term efficacy will be evaluated by means of a Alzheimer's Disease Assessment Scale(ADAS) and activities of daily living scale Disability Assessment for Dementia Scale(DAD)


Options:
A: Inclusion Criteria:

* Patients must have taken trial medication during the 24-month trial period of GAL-INT-8 and should be enrolled within 1 month after completion
* Patients and their primary caregiver give informed consent for the participation in the trial
* Patients must have remained in good health, as determined by medical history, complete physical examination and laboratory tests

Exclusion Criteria:

* If a patient developed, during the trial GAL-INT-8, symptoms of other neurological or psychiatric diseases that might contribute to dementia, the subject cannot be enrolled. This includes subjects developing neurodegenerative disorders such as Parkinson's disease, Pick's disease or Huntington's chorea, or Creutzfeldt-Jacob disease, and subjects with cognitive impairment resulting from stroke, acute cerebral trauma, hypoxic cerebral damage, infection or primary or metastatic cerebral neoplasia
* Subjects with the following co-existing medical conditions: a) Any history of epilepsy or convulsions except for febrile convulsions during childhood b) Peptic ulcer: if the ulcer is considered to be still "active", i.e., if treatment for this condition started \<3 months ago or if treatment is not successful (symptoms still present), the subject is not eligible. c) Clinically significant hepatic, renal, pulmonary, metabolic or endocrine disturbances
* Patients with current, clinically significant cardiovascular disease that would be expected to limit the subject's ability to complete a 12-month trial. The following would usually be considered clinically significant cardiovascular disease: a) Unstable angina
* angina or coronary artery disease that required a change in medication (anti-angina or digitalis) within the last 3 months b) Decompensated congestive heart failure i.e. when symptoms occur in a subject on stable medication during rest or light exercise (NYHA III and IV). Note: if the only signs of decompensation are pretibial or malleolar oedema and the exercise tolerance is still reasonable (absence of dyspnoea) the subject should not be excluded c) Cardiac disease potentially resulting in syncope, near syncope or other alterations of mental status
* In addition, the following conditions should lead to exclusion: atrial fibrillation without prophylactic treatment to prevent thromboembolic stroke, bradycardia \<50 beats/min., atrioventricular block \> first degree. d) Severe mitral or aortic valvular disease e) Hypotension or treatment for hypotension f) Systolic blood pressure greater than 170 mmHg or diastolic blood pressure greater than 110 mmHg
* Patients using any agent for the treatment of dementia (approved, experimental, including over the counter agents), including, but not limited to nootropic agents, cholinomimetic agents, choline, oestrogens taken without medical need, chronic NSAIDs (30 consecutive days), vitamin E more than 30 IU daily, and deprenyl
* Conditions that could interfere with the absorption of the compound or with the evaluation of the disease

4. Clinically significant agitation that requires treatment.
5. Severity of agitation defined by Cohen Mansfield agitation inventory (CMAI) \> /=45.
6. Age \>/= 55.

Exclusion Criteria:

1. Memantine usage in the 4 weeks prior to the start of the study.
2. On Cholinesterase inhibitor for less than 3 months and not on a stable dose.

6. Severe renal impairment.
7. Epilepsy, history of convulsions or seizure, or receiving any anti-epileptic treatment.
8. Concomitant usage of N-methyl-D-aspartate (NMDA) antagonists such as amantadine, ketamine or dextromethorphan.
9. Recent myocardial infarction, uncompensated congestive heart failure and uncontrolled hypertension.
10. Severe, unstable or poorly controlled medical illness.
11. Any disability that may interfere with the patient completing the study procedure.
12. Active malignancy.
13. Delirium, pain or any medical illness as a clear cause of agitation.
14. Any important drug interactions: Prohibited during study and in the 14 days preceding enrollment/inclusion are: Analgesic dextromethorphan, Dopaminergics- amantadine, Warfarin due to theoretical INR prolongation.
C: Inclusion Criteria:

* Ambulatory patients aged \>/= 50 years

* Confirmatory magnetic resonance imaging (MRI) or computed tomographic (CT) scan within the prior 12 months.
* Mini-Mental State Examination (MMSE) scores \>/= 3 and \</= 14 at Screening (Visit 1) and Baseline (Visit 2)
* Ongoing daily acetylcholinesterase inhibitor (AChEI) therapy at a stable dose for at least 3 months prior to Screening (Visit 1). It is preferred that patients continue to receive the same AChEI therapy for the duration of the study.

Exclusion Criteria:
