The three most commonly prescribed dementia drugs in Australia are Donepezil, Rivastigmine, and Galantamine, all cholinesterase inhibitors used for Alzheimer's disease, with Donepezil being the most frequent, followed by Rivastigmine and Galantamine, while Memantine (an NMDA receptor antagonist) is also used, especially for moderate to severe stages.
Prescriptions for dementia-specific medications
Some people who have used this medicine developed problems such as nausea, severe vomiting, loss of appetite, diarrhea, and weight loss. Talk with your doctor before using this medicine if you have any concerns.
You or the person who's unwell may also have a rash that's swollen, raised, itchy, blistered or peeling. These can be signs of a serious allergic reaction and may need immediate treatment in hospital.
The three most commonly prescribed dementia medications are typically Donepezil, Rivastigmine, and Galantamine, all cholinesterase inhibitors that boost acetylcholine for memory, with Donepezil often being the most prescribed. Memantine, which regulates glutamate, is also very common, often used with or for moderate-to-severe Alzheimer's.
Donanemab, like lecanemab, is a type of drug called a monoclonal antibody. Antibodies form part of our immune system and bind to harmful proteins to destroy them. Donanemab contains antibodies that bind to a protein called amyloid, which builds up in the brain in the early stages of Alzheimer's disease.
The number one cause of dementia is Alzheimer's disease, responsible for 60-80% of cases, characterized by brain plaques (beta-amyloid protein) and tangles (tau protein) that damage nerve cells, leading to progressive memory and cognitive decline, though vascular dementia from blood vessel damage is also a significant factor.
Side effects of memantine
Headaches. Dizziness or problems with balance. Tiredness or shortness of breath. Raised blood pressure.
IR/Immediate Release dosage frequency is once or twice a day: • Initial dose is 5mg once a day week one; 5mg twice a day week 2; 10mg in the morning and 5 mg at night week 3; to the maximum dose 10mg twice a day.
Memantine is not suitable for some people. To make sure it's safe, tell your doctor if you, or the person you're caring for, have: ever had an allergic reaction to memantine or any other medicine. epilepsy or have ever had a seizure or fit.
heart problems, such as an irregular or slow heartbeat. asthma or other lung disease such as chronic obstructive pulmonary disease (COPD) ever had a seizure or fit. a condition that makes it difficult to pee.
The off-label antipsychotics most often used for patients with dementia are: quetiapine and clozapine – These drugs are mostly used if a person has dementia with Lewy bodies or Parkinson's disease dementia. This is because they interfere less with drugs that treat other symptoms of these conditions.
Key points about vascular dementia
Symptoms can include problems with memory and focus, confusion, changes in personality and behavior, loss of speech and language skills, and sometimes physical symptoms, such as weakness or tremors.
Memantine may help slow the decline in memory and thinking skills. It also may play a role in protecting nerve cells. Memantine is approved to treat moderate to severe Alzheimer's disease. It's usually taken as a pill or liquid twice a day or as an extended-release pill once a day.
Donepezil and rivastigmine
Donepezil tablets are by far the most common medication used to treat dementia. Rivastigmine tends only to be used when donepezil causes side effects, or if the person can't take it for medical reasons.

Missing doses may result in a return of symptoms like anxiety, depression, or irritability. In some cases, abrupt changes in the level of these medications in your system can cause withdrawal symptoms. What to Do: If you miss a dose, take it as soon as you remember, unless it's almost time for your next dose.
Memantine is a medicine for dementia. It is used to treat memory loss which is one of the main symptoms of dementia.
Cautions with other medicines
ChEIs currently approved for the treatment of AD include donepezil, rivastigmine, and galantamine, which are primarily used for the treatment of mild to moderate AD. In contrast, memantine is primarily used for the treatment of moderate to severe AD.
When someone gets the diagnosis of dementia, a cure is only very rarely possible (see p2 About Reversible Dementias). In the current issue of Neurology, Sacks and Shulman1 report one of these rare cases of a reversal of dementia involving a patient on steroid medication.
Should Memantine be taken at night? Memantine can be taken at any time of the day. You must remember to take this medication at the same time every day. Since it may cause a feeling of drowsiness after consumption, you can take it at night to prevent the common side effects associated with Memantine, like sleepiness.
Our results confirm that vitamin D deficiency is associated with a substantially increased risk of all-cause dementia and Alzheimer disease.
The "2-finger test" for dementia involves an examiner showing a hand gesture (like interlocking index and middle fingers) and asking the patient to copy it, testing motor skills, visual memory, and coordination, as difficulties can signal early cognitive decline, but it's a screening tool, not a definitive diagnosis, prompting further medical evaluation. Other related tests include finger-tapping and finger-to-nose, looking for hesitation or misjudgment in movement.
But Romano says it's a leap to say that skipping breakfast actually causes dementia. “Alzheimer's disease is a complex brain illness,” he says. “Although the study found these correlations between skipping breakfast and dementia, skipping breakfast might be an indicator of other health habits or life circumstances.”
