Medications
Make Alzheimer’s Disease Patients Worse
A recent study in
the United Kingdom has found that antipsychotic drugs which are
commonly given to Alzheimer’s patients, frequently make their
condition worse. These drugs are now believed according to the study,
to provide no benefit for patients with mild behavioral problems, but
at the same time may cause marked deterioration in verbal skills. The
research focused on 165 people who are living in nursing homes in four
British cities who had advanced Alzheimer’s disease. It is estimated
that as many as 60% of Alzheimer’s disease patients living in nursing
homes, may be given these drugs to control aggression and other
behavioral problems at some point in time. This study was recently
reported in the journal Public Library of Science Medicine.
Case study:
According to a
story reported by BBC News, Rita Clark from Cleveland Ohio, said her
husband was diagnosed with Alzheimer’s disease approximately 7 years
ago. She stated that: “My husband developed a range of side effects
while receiving antipsychotic drugs. Since the drugs have been
withdrawn, the side effects have gone a he generally seems much better
and more settled.. I’m not saying it’s the same for everyone, but in
my husband’s case, withdrawing the drugs has led to a clear
improvement in his quality-of-life.”
The researchers in
this study from the universities of Oxford and Newcastle, and from
King’s College in London, have concluded that the antipsychotic
medications offered no long-term benefit for most patients with mild
symptoms of disturbed behavior.
Many patients
showed a marked deterioration in their verbal fluency within six
months of treatment. Additional preliminary analysis currently being
conducted on the data, seems to suggest that the use of antipsychotic
medications may also increase mortality rates. Research was focused
on patients living in nursing homes in Newcastle, Edinburg, London and
Oxfordshire. All of the patients in this study were taking
antipsychotic medications or what are frequently referred to as
neuroleptics for at least three months, and were continued on the same
medication for an additional 12 months, or took a nonactive, dummy
pill. Professor Clive Ballard, who is the lead researcher on the
study stated that: “It is very clear that even over a six-month period
of treatment, there’s no benefit for neuroleptics in treating the
behavior in people with Alzheimer’s disease when the symptoms are
mild”. He also went on to conclude that: “For people with more severe
behavioral symptoms, balancing the potential benefits against adverse
effects is more difficult.”
Rebecca Wood from
the Alzheimer’s research trust stated: “These results are deeply
troubling and highlight the urgent need to develop better treatments.”
The trust concluded that antipsychotic medication should only be
prescribed long-term to dementia patients with severe behavioral
problems, and then probably only as a last resort when all other
nondrug options have failed.
Additional risks for stroke:
Neil Hunt of the
Alzheimer’s Society has concluded that previous research has also
found a higher risk for stroke and death when neuroleptic drugs are
used for people with dementia. He stated:” This widespread
overprescription to people with dementia must stop”. “It is time we
stop wasting money giving people drug treatments with no benefit and
start investing in good-quality dementia care.”
It is believed
that an estimated 700,000 people are affected with dementia in the
United Kingdom, a number that should double in the next 30 years. An
additional report on the use of antipsychotics in care homes will be
published by the All-Party Parliamentary Group on dementia later this
month. Jeremy Wright, group chairman stated: “We urgently need to
ensure people with dementia are only prescribed drugs as a last
resort, not as an easy option. We will set out simple changes that
must be made to stop this abuse when we publish our findings at the
end of April.”
The medications
that were referred to in the study which came under analysis were
risperidone (Risperdal), thioridazine (Melleril), chlorpromazine
(Largactil), haloperidol (Serenace), and trifluoperazine (Stelazine).
