Drugs prescribed for patients with Alzheimer's disease can be broadly classified in three categories: drugs for dementia, which aim to enhance cognitive function and delay progression of symptoms of the disease, at least in the short term; drugs acting on the central nervous system, such as antipsychotics, antidepressants, hypnotics and anxiolytics, which aim to ameliorate neuropsychiatric symptoms; and drugs prescribed for other medical conditions that are common in this age group.

Which drugs are used in the treatment of Alzheimer’s disease?
National Institute for Health and Care Excellence Donepezil, galantamine, rivastigmine and memantine for the treatment of Alzheimer’s disease. London: NICE; 2011. Available online at www.nice.org.uk/guidance/ta217/chapter/3-The-technologies.
How effective is tacrine for Alzheimer's disease?
Tacrine is the first drug approved by the FDA for treatment of Alzheimer's disease. Although it may improve psychometric test scores in mild to moderately impaired patients, it is not a panacea and does not affect the course of the disease. Patients must be monitored closely for elevated transaminas …
How can we improve clinical outcomes for Alzheimer’s disease?
Better selection of patients for clinical trials may yield more favourable clinical outcomes. For example, the ‘mild to moderate’ AD group may be too heterogeneous, and treatment effects within subgroups could be lost, as seen in the solanezumab trials.
How many therapies have been approved for Alzheimer’s disease?
Five therapies have been approved for AD. Four of these medications are classified together as cholinesterase inhibitors (CIs); these are approved for dementia of the Alzheimer’s type in the mild-to-moderate stage.
How does medication affect Alzheimer's?
Although current medications cannot cure Alzheimer's, one treatment addresses the underlying biology. Other medications may help lessen symptoms, such as memory loss and confusion.
Which of the following are drugs used to treat Alzheimer disease?
Three cholinesterase inhibitors are commonly prescribed:Donepezil (Aricept) is approved to treat all stages of the disease. It's taken once a day as a pill.Galantamine (Razadyne) is approved to treat mild to moderate Alzheimer's. ... Rivastigmine (Exelon) is approved for mild to moderate Alzheimer's disease.
What is the major goal of treatment for the patient with Alzheimer's disease?
The primary goals of treatment for Alzheimer's are to improve the quality of life for the person suffering and for his or her caregiver(s).
What are the side effects of cholinesterase inhibitors?
The most common adverse effects of cholinesterase inhibitors include nausea, diarrhea, vomiting, decreased appetite, dyspepsia, anorexia, muscle cramps, fatigue, insomnia, dizziness, headache, and asthenia. Taking these medications with food, preferably a full meal, can mitigate these gastrointestinal effects.
How do cholinesterase inhibitors work in Alzheimer disease?
Cholinesterase inhibitors result in higher concentrations of acetylcholine, leading to increased communication between nerve cells, which in turn, may temporarily improve or stabilise the symptoms of dementia.
How does Alzheimer's affect the brain?
Alzheimer's disease is a progressive neurologic disorder that causes the brain to shrink (atrophy) and brain cells to die. Alzheimer's disease is the most common cause of dementia — a continuous decline in thinking, behavioral and social skills that affects a person's ability to function independently.
Can medication slow down Alzheimer's?
There are no drug treatments that can cure Alzheimer's disease or any other common type of dementia. However, there are medicines for Alzheimer's disease that can ease symptoms for a while, or slow down their progression, in some people.
Which drug for Alzheimer's disease should be administered beginning at the time of diagnosis?
Donepezil, galantamine and rivastigmine can be prescribed for people with early- to mid-stage Alzheimer's disease. The latest guidelines recommend that these medicines should be continued in the later, severe, stages of the disease.
What is the purpose of Aducanumab?
Aducanumab (brand name Aduhelm) is a monoclonal antibody engineered in a laboratory to stick to the amyloid molecule that forms plaques in the brains of people with Alzheimer’s. Most researchers believe that the plaques form first and damage brain cells, causing tau tangles to form inside them, killing the cells.
What happens if aducanumab is stuck to a plaque?
Once aducanumab has stuck to the plaque, your body’s immune system will come in and remove the plaque, thinking it’s a foreign invader. The hope and expectation are that, once the plaques are removed, the brain cells will stop dying, and thinking, memory, function, and behavior will stop deteriorating.
Does aducanumab slow down dementia?
As mentioned above, the known side effects are that 30% of people experienced reversible brain swelling and more than 10% had tiny brain bleeds. Although it does clear the amyloid plaques from the brain, we don’t know if it will slow down the dementia or not.
How often do you need an intravenous infusion for a syringe?
How do you take the drug and is it safe? To take the drug, you need an intravenous infusion every four weeks — forever. Thirty percent of those who took the drug had a reversible swelling of the brain, and more than 10% had tiny brain bleeds.
Can you get Alzheimer's with a PET scan?
There are other causes of these problems as well. To determine if Alzheimer’s is present, you need to get either an amyloid PET scan or a lumbar puncture to be sure you have the amyloid plaques of Alzheimer’s.
When was Aduhelm approved for Alzheimer's?
A new Alzheimer’s drug has been approved. But should you take it? On June 7, 2021, the FDA granted accelerated approval to aducanumab (brand name Aduhelm), the first drug in 18 years for Alzheimer’s disease.
Is the CDC relaxed?
The CDC has relaxed some prevention measures, particularly for people who are fully vaccinated, and especially outdoors. Meanwhile, scientists continue to explore treatments and to keep an eye on viral variants. Stay Informed. View Coronavirus COVID-19 Resource Center.
