It was not until 1901 that German psychiatrist Alois Alzheimer identified the first case of what became known as Alzheimers disease, named after him, in a fifty-year-old woman he called Auguste D. He followed her case until she died in 1906 when he first reported publicly on it. During the next five years, eleven similar cases were reported in the medical literature, some of them already using the term Alzheimers disease. The disease was first described as a distinctive disease by Emil Kraepelin after suppressing some of the clinical (delusions and hallucinations) and pathological features (arteriosclerotic changes) contained in the original report of Auguste D. He included Alzheimers disease, also named presenile dementia by Kraepelin, as a subtype of senile dementia in the eighth edition of his Textbook of Psychiatry, published on 15 July, 1910.For most of the 20th century, the diagnosis of Alzheimers disease was reserved for individuals between the ages of 45 and 65 who developed symptoms of dementia. The terminology changed after 1977 when a conference on Alzheimers disease concluded that the clinical and pathological manifestations of presenile and senile dementia were almost identical, although the authors also added that this did not rule out the possibility that they had different causes. This eventually led to the diagnosis of Alzheimers disease independent of age. The term senile dementia of the Alzheimer type (SDAT) was used for a time to describe the condition in those over 65, with classical Alzheimers disease being used to describe those who were younger.
Kato stated that leaving behind cities and going into rural areas, he could find many traces of animism, fetishism, and phallicism.Kato Genchi stated that the Ten Sacred Treasures were fetishes and the Imperial Regalia of Japan retained the same traits, and pointed out the similarities with the Pusaka of the natives of the East Indies and the Tjurunga of the Central Australians. The Kusanagi no Tsurugi was believed to provide supernatural protection (blessings) through the spiritual experience of the divine sword, and the Kusanagi no Tsurugi was deified and enshrined at Atsuta in Owari Province, which is now the Atsuta Shrine.Akaruhime no Kami, the deity of Hiyurikuso Shrine, was said to be a red ball. In the Kami era, the jewel around Izanagi-no-Mikotos neck was deified and called Mikuratana-kami.William George Aston remarked that the sword at Atsuta Shrine was originally an offering and later became a sacred object, as an example of Fetishism. Sword was one of mitama-shiro (spirit representative, spirit-token), or more commonly known as the shintai (god-body). He observed that people tends to think of the mitama (spirit) of a deity first as the seat of his real presence, and second as the deity itself. Many people do not distinguish between mitama (spirit) and shintai (god-body), and some even confused shintai (god-body) with the gods real body. For example, cooking furnace (kamado) itself was worshipped as god.
