Research and Alzheimer’s Disease Stem cell research
has been showing promise in the treatment of certain neurological
diseases such as Parkinson’s disease, Huntington’s chorea, and spinal
cord injuries. But can stem cell research mean much to the treatment of
Alzheimer’s disease, or is this form of research better off treating
illnesses with less complicated structures?
A Controversial Method
Stem cell research is undoubtedly a controversial method of
treatment and research. People have argued against stem cell research
primarily from a religious standpoint, as they claim the procedure is
immoral and wrong. Yet, embryonic stem cell research does not require
the destruction of fetuses, nor does it require scientists to create or
clone human beings. The method is practiced in other countries outside
the United States but continues to meet roadblocks and barriers within
the United States.
Too Complicated?
The question becomes whether treating Alzheimer’s disease
with stem cell research is going to be a successful endeavor, and the
answer remains that scientists are not sure. While the treatment has
shown success at treating diseases that are more generalized within the
neurological system such as Parkinson’s disease, it has not been studied
as thoroughly for treatment with Alzheimer’s patients. This is
primarily because Alzheimer’s disease affects a wide area of the
brain—virtually the entire cerebral cortex. This makes it difficult for
scientists to deliver the stem cells to the brain concisely and makes
the procedure much more complicated and complex.
Since diseases like Parkinson’s are generally more
localized, it is easier to treat those specific areas of the brain.
Scientists have not determined that treating Alzheimer’s disease with
stem cell research is practical. Some scientists have speculated that
they could locate certain dormant cells within the brain that have not
yet been destroyed and effectively switch them on. If the cells could be
stimulated to become the right kind of cell to replace the destroyed
nerve cells in the brain and could be stimulated to divide rapidly
enough, the cells could then be moved to damaged parts of the brain to
replace those cells. This remains a complicated procedure and one that
is simply not practical in treating the majority of patients living with
Alzheimer’s disease. Research on stem cell treatment continues,
however, and new developments are being made in hopes of making the
procedure less complex.
