It seems that people from English-speaking countries have become lazier than before, and they just wait for others to learn their ways of communication waysng and language.

Learning English is good not only it is increasing to be a living languagebecause it is becoming more and more widely used, but also an effective way to practice oury brains.

My father has been living with Alzheimer's disease for about 10 years, and his condition worsened two years ago following the injection of the COVID-19 vaccine, although no doctors would like to confirm it.

However, just one or two months after the vaccination, he on longer recognized me and completely forgot how to play chess at all.

Learning English is not only it isan increasing to be a living languagely practical language to learn, but also an effective way to practicexercise oury brains.

You practice a sport, or piano or a language but not your brain.

I want to join them; not only help them, but also aid my father and myself.

Given that bilingual language learners can be good for maintaining a healthy brain, I boldly personally speculate that if fewer native English-speaking people stop learning foreign languages, they might face a higher risk of Alzheimer's disease in the future.

Of course, this disease can result from various factors, and discontinuing language learning might only be one of them.

A few days ago, I came across a piece of interesting news which said that fewer native English speakers are learning foreign languages.

Meanwhile, more non-native English-speaking people are struggling with English, - including myself.

It seems that people from English-speaking countries have become lazier than before, and that they just wait for others to learn their communication ways and language.

"Ways of communication" sounds more natural than "communication ways" but both options are redundant in this sentence

I also noticed thatcame across some sources that had provedn that bilinguals people have fea lower chances of being affected by dementia-related problems such as Alzheimer's disease.

My father has been living with Alzheimer's disease for about 10 years, and his condition worsened two years ago following theafter he received an injection of the COVID-19 vaccine, although noI have not found any doctors who would like to confirm ithis.

Before thehis vaccination, my father could slowly play Chinese chess with his friends slowly, and call me by my name.

However, just one or two months after thehis vaccination, he ono longer recognized me and forgot how to play chess at allltogether.

Learning English is not only it is increasing to be a living language, but also an effective way to practiceuseful because it has become increasingly necessary for the modern world, but also because it is an effective way to take care of the long term health of oury brains.

These changes are a bit heavier than before but I think something like this is the gist of what you were trying to say here

Several days ago, I read an advertisement thatsaying that there is a non-profit agency isorganization seeking volunteers to assist Alzheimer's patients.

"non-profit organization" is probably what you meant to write here. The term "non-profit agency" isn't really something a native speaker would ever say, even though we would know what you meant to say if you did say agency instead.

I want to join them; not only to help them, but also to aid my father and myselfI.

Given that bilingual language learners can be good for maintaining a healthy brain, I boldly personally speculate that if fewerlearning another language is very useful for maintaining a healthy brain, I believe that if the number of native English-speaking people stop learning foreign languages, continues to decline, then they might face a higher risk of Alzheimer's disease in the future.

It might be more natural to phrase the last part as "...then the rate of Alzheimer's disease among native English speakers will continue to increase in the future." What you wrote is grammatically correct though

Of course,Even though this disease can result from various factors, and disconthas potentially many different contributing factors, I believe that a declinuing rate of language learning mightcould be one of them.
