2020 was consumed by COVID-19.  According to the Centers for Disease Control, the full name is coronavirus disease 2019, abbreviated to COVID-19.  ‘CO’ stands for ‘corona,’ ‘VI’ for ‘virus,’ and ‘D’ for disease.  The ‘19’ is for the year it was first identified in Wuhan, China in December of 2019.

COVID-19 is a clinical/scientific name, but others, like Alzheimer’s disease, are named for people.

Like Crohn’s disease, Duchenne muscular dystrophy, or Hodgkin disease, Alzheimer’s disease bears the name of the man who first documented it – Dr. Alois Alzheimer, a German psychiatrist and neuropathologist born in Bavaria in 1864.

Around the year 1901, Dr. Alzheimer, who had been studying senile illnesses, crossed the path of a woman named Auguste Deter, who was a patient at the asylum in Frankfurt, Germany.  Deter was 51 years old, and suffering from a variety of strange symptoms, including loss of short-term memory.

Deter had begun showing symptoms of dementia in the late 1890’s and her husband had her admitted to the Frankfurt facility in 1901.

Dr. Alzheimer began five years of intense study of Deter.  His notes indicate that she was barely able to remember key elements of her life, had little or no sense of time and place, had rapid mood swings and was frequently incoherent or lost in her responses to questions.

Alzheimer studied her until her death in 1906, after which he had her medical records and brain brought to his laboratory in Munich.  There, he was able to identify what we also know today as amyloid plaques and neurofibrillary tangles – the signposts of Alzheimer’s disease.  Deter would in fact have been diagnosed with early onset Alzheimer’s disease by today’s standards.

Dr. Alzheimer passed away in December of 1915 at the age of 51 from what was probably a streptococcal infection.  He was remembered by friends and colleagues as a devoted instructor and researcher. He left behind three children, and his wife pre-deceased him.

Over a century after his discovery, the Alzheimer’s Association works with physicians and scientists all over the planet who are carrying on what was begun by Dr. Alzheimer.   The annual Alzheimer’s Association International Conference® attracts thousands of scientists and physicians from over 70 nations and is the world’s largest gathering of Alzheimer’s and dementia researchers.  Additionally, the Association funds research that moves knowledge of the disease forward, yielding clues to causes and treatments.
