In summary, PD is a progressive loss of dopaminergic neurons in the brain, which can lead to the development of symptoms such as movement problems, difficulty speaking, and memory loss. Alzheimer's is a far more serious and fatal form of degenerative brain disease, which affects the whole nervous system.

Is fatal degenerative brain disease inevitable? If we could transplant ourselves into clones every 20 years or something like that, how long would we be able to live before degenerative brain disease, or something like that, killed us?

There is a progressive loss of dopaminergic neurons of the brain as we age, somewhere close to 13% per decade after age 45 (some loss occurs before this time as well, it's just not as rapid). This is the type of neuron which is lost in Parkinson's disease (PD). In order to develop symptoms of PD a certain threshold limit of damage must be attained, believed to be about 70% neuron loss, once this happens clinical symptoms of PD can occur. Certain people in a population may be more prone to developing this, others not, its not a completely understood disease and is generally termed idiopathic PD, because the cause is unknown. There is also an early-onset PD which strikes rather young people, Michael J. Fox for example, and some forms of heritable familial PD. This is the brain region/disease I am most familiar with, so there may be other examples, Alzheimer's and Amyotrophic lateral sclerosis come to mind.

Most people will not live long enough to encounter the above mentioned threshold, but it is always there and if we were somehow able to extend our lives, more and more degenerative processes would be be un-masked and we would eventually die, or suffer, from those.

So we would eventually suffer, (If we lived a really long time) but not necessarily die, from degenerative processes?
 
  • #4
PD is not fatal, Alzheimer's is.

The degenerative brain disease is so severe one which affects the whole nervous system.
Degenerative nerve diseases cause worsening of many of your body's activities, including balance, movement, talking, breathing and heart function. Many of these diseases are genetic, which means they run in families or you have a genetic mutation.

What is degenerative brain disease?

Degenerative brain disease refers to a group of conditions that cause progressive deterioration of brain cells and their functions. This can lead to a decline in cognitive abilities, movement, and other bodily functions.

What are the common types of degenerative brain disease?

The most common types of degenerative brain disease include Alzheimer's disease, Parkinson's disease, Huntington's disease, and amyotrophic lateral sclerosis (ALS). These diseases have different underlying causes and symptoms, but they all involve the degeneration of brain cells.

What are the risk factors for developing degenerative brain disease?

Some risk factors for degenerative brain disease include age, family history, genetics, head injuries, and certain lifestyle choices such as smoking and excessive alcohol consumption. However, the exact causes of these diseases are still being studied.

What are the symptoms of degenerative brain disease?

The symptoms of degenerative brain disease vary depending on the type and severity of the disease. However, common symptoms include memory loss, difficulty with movement and coordination, changes in mood and behavior, and difficulty with speech and language.

Is there a cure for degenerative brain disease?

Currently, there is no cure for degenerative brain disease. However, there are treatments available that can help manage symptoms and improve quality of life. Ongoing research is being conducted to better understand these diseases and develop potential cures or preventive measures.
