Detection of beta amyloid protein as alzheimer's disease-causing factor in palatine tonsil and use thereof

A method for determining and treating patients subject to tonsillectomy, the method comprising:

• a) measuring an expression level or beta amyloid plaque accumulation level of beta amyloid in a tonsillar sample derived from a subject;
• b) determining that the higher the expression level or beta amyloid plaque accumulation level of beta amyloid in the step a) is compared to an expression amount of normal people, the subject is determined to be a subject for tonsillectomy;
• and
• c) performing a tonsillectomy on the subject determined in step b).

A method for determining and treating a subject with Alzheimer's disease, the method comprising:

• a) measuring an expression level of Staphylococcus aureus strains in a tonsillar sample obtained from a subject;
• b) determining that the higher the expression level of Staphylococcus aureus in the step a) is compared to an expression amount of normal people, the higher the risk of developing the Alzheimer's disease;
• and
• c) performing a tonsillectomy on the subject determined in step b).
