Description:
BACKGROUND OF THE INVENTION 
       [0001]    The present invention relates to methods and systems for treatment of Alzheimer disease. 
         [0002]    Alzheimer disease affects millions of people worldwide. It affects brain functions of people suffering from the disease, which results in loss of memory, inability of functioning in everyday life, inferior interaction with other people and environment, and other highly negative effects. It is believed that the disease causes disruption of cell-to-cell communication and also transportation of essential materials such as nutrients and organelles in the brain of a person suffering from the disease. 
         [0003]    The reason for this disruption is a formation in the brain of structures or lesions which are on the way of the above specified communication and transportation, such as amyloid plaques, neurofibrillary tangles etc. While amyloid plaques are located between the neurons and form clusters of beta-amyloid molecules, neurofibrillary tangles are found inside the neurons of the brain and form a thick insoluble mass of defective tau proteins which twists filaments or microtubules responsible for the transportation process. 
         [0004]    Some medications and treatment methods have been tested, however it is believed that the treatment methods can be improved to more efficiently treat Alzheimer disease.

         [0020]    The novel features of the present invention are set forth in particular in the appended claims. 
         [0021]    The invention itself however both as to its subject matter and manner of operation, will be best understood from the description of the preferred embodiments. 
     
    
     DESCRIPTION OF THE PREFERRED EMBODIMENTS 
       [0022]    According to the present invention which is set forth in the patent application, a patient which has symptoms of Alzheimer diseases has to be subjected first to examination for diagnostic purposes. 
         [0023]    The examination can be conducted in accordance with known procedures and with known means or equipment, which first includes determination of external factors which are symptomatic of the disease. Once it is determined that the patients symptoms are indicative of Alzheimer disease, the patient needs to undergo examination of his/her brain, which can include for example X-ray, Magnetic Resonance Imaging, and other. The objective of the tests is to clarify the location of abnormal lesions or structures in the brain. 
         [0024]    Once the location of the lesions, which are formed by amyloid plaques and neurofibrillary tangles, the lesions in the brain of a patient and a brain liquid in the vicinity of them are subjected according to the present invention to a non-invasive action which cause a cavitation in the brain liquid (fluid) near the lesions by corresponding means which cause the cavitation process. The cavitation which is carried out is a non-inertial cavitation and carried out non-invasively, induces in the environment of the brain liquid (fluid) near the lesions nano-cavities or nano-bubbles which causes a mechanical agitation destroying the lesions. 
         [0025]    Corresponding means produce actions which propagate through a brain or bran&#39;s tissues and interact with a liquid in the brain, create a cavitation process in it resulting in formation of nano-bubbles. When the nano-bubbles can oscillate meet on their way a dense material of the lesions, they collapse and destroy them. As a result, transportation of essential materials and transmission of information in the brain can be restored. 
         [0026]    In addition the cavitation enhances circulation processes in lymphatic vessels in the brain and therefore enhances transportation of the products of destruction of the lesions which are responsible for Alzheimer disease. The enhanced circulation processes in the brain liquid also prevents formation of new lesions. 
         [0027]    Various processes and means or equipment which generate cavitation can be utilized according to the present invention. 
         [0028]    The non-invasive action which generates cavitation processes in the brain liquid near the lesions in the patient&#39;s brain can be executed, for example, by using electric current pulses, in particular remotely applied induction current pulses, directed to the brain and thus to the lesions and the brain fluid around them by means or an apparatus generating and directing such current pulses. In particular electric current can be simulated by electromagnetic induction. A magnetic field generator or coil can be placed near the head of a patient and produce electric current in the region of the brain just under the coil. The magnetic field pulses of about 10-20 Hz reach into the brain for 1-5 cm and can induce electric current of 0.1-10 mA causing cavitation. The treatment can continue for several minutes. 
         [0029]    The non-invasive action which generates cavitation processes in a brain liquid near the lesions in the patient&#39;s brain can be executed, for example, by using laser pulses directed to the brain and thus to the lesions and the brain liquid around them, with the use of such means as a corresponding laser generator. A laser beam generator can generate infrared radiation with a wave length 5-10 mcm of 1-10 Wt and pulses f 60-150 ns. Its power is enough to penetrate 6-7 cm, following by low energy supply of 10-100 Wt to induce cavitation. 
         [0030]    The non-invasive action which generates cavitation processes in the lesions in the patient&#39;s brain can be executed, for example, by using acoustic pulses directed to the brain and thus to the lesions and the brain liquid around them. An electronic sonic generator with a driver, an amplifier and a transducer can generate a sine, pulse or square waves within a range of 20-200 Hz and SPL of 130 DB. Acoustic vibrations aimed at the brain can start with lower frequencies of shorter length of 10 msec and increase to 2 sec. 
         [0031]    The sessions can be repeated 2-3 times a day. The cavitation process in brain liquid (fluid) caused in the lesions loosens the amyloid plaques and neurofibrillary tangles, etc. and eventually they disappear. Periodical examinations of the brain should be then conducted to follow the progress of the cavitation-induced loosening of the lesions until they are completely cleared. 
         [0032]    It is further possible to cause cavitation processes for the treatment by steps and means providing various combinations of the electric current pulses, laser pulses, and acoustic pulses, in accordance with the present invention 
         [0033]    According to the present invention, it is also suggested that a patient which is subjected to the above described non-invasive cavitation-causing treatment, are given by corresponding means gamma-globulin, preliminarily to the cavitation-causing actions and also between the treatment sessions. Gamma-globulin intake stimulates immune system and also protects healthy matter of the brain from a damage. On the other hand, the cavitation process can elimination possible infections which can be accidentally present in the gamma-globulin 
         [0034]    It should be mentioned that the present invention is not limited to the details shown since various modifications and changes are possible without departing from the spirit of the invention.
