1989年（18）

After graduating from high school, I worked as a local government's technical engineer and was subsequently transferred to and worked for several public organizations.
I married a woman from my hometown and had a child. However, we divorced around the same time I was transferred to Hokkaido.
Over 30 years, I lived an irregular, work-centered life. For example, I usually had dinner after 1:00 a.m. and slept 3 to 4 hours a night.

While working for a public organization, I collapsed and was diagnosed with transient cerebral ischemic attack (mild cerebral infarction). The doctor instructed me to take a rest, but I was unable to concentrate on resting and receiving treatment because I was engaged in reconstruction assistance work after the Great East Japan Earthquake. I returned to work immediately.
However, after returning to work, I began to feel something was slightly wrong in my daily life.

I became a university employee through a public-private personnel exchange and left the technical position to take on my first human resources work. However, 3 months later, I contracted influenza. After that, I became unable to understand what the materials I created (e.g., in Excel) meant. Even after creating a manual for myself, I could not cope with it.
I was suspected of having dementia and was hospitalized to undergo an MRI and other examinations. I became completely unable to use numbers and increasingly forgetful.
I became unsure about my commuting route. Although I could take only one JR line to work, I would take the subway by mistake or get off at the wrong station on the way.
I became unable to even endure crowded trains and did not even know what symptoms I was having. I went back to the hospital affiliated with my workplace for examination.

Diagnosis

2019年（48）

In April, I completely retired from the university and the public institution. Unable to accept the diagnosis of juvenile dementia, I did Chinese character and numerical drills in the hope of stimulating the brain to function again.
Examinations revealed that my brain was not receiving enough oxygen. I will be treated with CPAP, and I am hoping that my brain will recover by taking in enough oxygen.
I am willing to work, and my doctor has not told me not to. However, due to my sense of responsibility, I am hesitant because I might not be able to fulfill my duties.
I applied for public assistance in June, and the application was approved in July. In addition, I have been consulting a social worker to see if I could receive a disability pension, but the situation continues to be very difficult.
In July, I was introduced to a community comprehensive support center. Living alone, I have been in contact with the center so that I will not cause any inconvenience if something happens to me.
