Is Alzheimer’s Disease a Concern for the Young?

The research findings suggested that early-onset Alzheimer's disease should get more attention. Investigating the unanswered problems surrounding Alzheimer's disease in younger patients may emerge as one of the most difficult scientific challenges in the years to come.

According to the findings of a research that was recently presented in the Journal of Alzheimer's Disease, A group of neurologists working at a memory clinic in China has given a 19-year-old man a diagnosis that they believe to be Alzheimer's disease. This individual is now the youngest person in the world to be given a diagnosis with Alzheimer's disease.

Researchers from Capital Medical University's Xuanwu Hospital in Beijing found that an adolescent's memory had gradually deteriorated over the course of two years and had characteristics that were strong markers of Alzheimer's disease. These characteristics included memory loss and hippocampal atrophy, which is a shrinkage that is an early sign of the disease.

The imaging of the patient's brain revealed that the hippocampus, an area of the brain important in memory, had shrunk, and the patient's CSF fluid suggested the presence of typical indicators of the most prevalent type of dementia.

Early-onset Alzheimer's disease (AD), which affects individuals under the age of 65 and accounts for up to 10 percent of all diagnoses, is often thought of as a condition that only affects elderly people. However, this is not the case.

About all individuals with Alzheimer's disease who are under the age of 30 may have their condition explained by pathogenic gene mutations, which places them in the category of familial Alzheimer's disease. When a person is diagnosed at an earlier age, it is more probable that the condition is the consequence of a defective gene inherited from their family.

Nevertheless, researchers from the Capital Medical University in Beijing could not detect any of the typical mutations responsible for the early beginning of memory loss, nor did they identify any questionable genes after searching the whole genome.

Before this current diagnosis, the youngest patient diagnosed with Alzheimer's disease in China was 21 years old. They contained the PSEN1 gene mutation, which is responsible for the accumulation of aberrant proteins in the brain and the formation of clusters of toxic plaques, a distinctive aspect of Alzheimer's disease.

Instances like the most recent one that occurred in China provide somewhat of a riddle. The fact that the 19-year-family old's did not have a history of Alzheimer's disease or dementia makes it difficult to classify the condition as FAD. On the other hand, the young man did not have any ailments, infections, or head injuries that may explain his abrupt cognitive impairment.

The adolescent patient had difficulty concentrating in school for the previous two years before being sent to the memory clinic. Sometimes he was unable to recall what had happened the previous day, and he was notoriously bad at keeping track of his personal possessions. Reading became difficult for him as well, and he had a decrease in his short-term memory.

In the end, the young man's cognitive loss became so severe that he could not complete high school, even though he could still live on his own.

One year after being sent to the memory clinic, he demonstrated declines in his immediate recollection, short-delay recall after three minutes, and long-delay recall after thirty minutes.

The patient's score on the full-scale memory test was 82 percent lower than that of peers the same age as him, and his score on the immediate memory test was 87 percent lower.

Nonetheless, his medical team has said that the patient is "changing our view of the average age of beginning of AD." Long-term follow-up is required to corroborate the young guy's diagnosis.

According to the findings of neurologist Jianping Jia and colleagues, "the patient had extremely early-onset AD with no identifiable causal mutations," which indicates that the disease's pathophysiology still needs to be investigated.

The case study illustrates that Alzheimer's does not follow a single road and is far more complicated than we imagined, emerging through various paths with varied impacts. This is shown by the fact that Alzheimer's does not follow a single pathway.

The neurologists who recounted the patient's case to the South China Morning Post suggested that future research should concentrate on instances with an early beginning to increase our knowledge of memory loss further.

They forecast that one of the most difficult scientific challenges of the future will be how to understand better the symptoms and behaviors of Alzheimer's disease in younger patients.
