Definition of Alzheimer's. 1  Alzheimer's disease is a progressive, degenerative disorder that attacks the brain's nerve cells, or neurons, resulting in loss of memory, thinking and language skills, and behavioral changes. Origin of the term Alzheimer's disease dates back to 1906 when Dr. Alois Alzheimer, a German physician, presented a case history before a medical meeting of a 51-year-old woman who suffered from a rare brain disorder. 2  A brain autopsy identified the plaques and tangles that today characterize Alzheimer's disease.
Since the release of the first novel, Harry Potter and the Philosopher's Stone, on 30 June 1997, the books have gained immense popularity, critical acclaim and commercial success worldwide.
There is also the famed Ted Smart edition of Harry Potter and the Philosopher's Stone. A first edition of this book, printed a year after the first edition yet still appearing the same visually, can reach Â£300 and a second edition up to Â£30. Still a good amount but a far cry from the what the true firsts can achieve.
