is there any medicine available for the disease in context?
Acetylcholinesterase inhibitors such as tacrine, rivastigmine, galantamine and donepezil. An NMDA receptor antagonist such as memantine.  No medication has been clearly shown to delay or halt the progression of the disease.
Alzheimer's disease
Five medications are currently used to treat the cognitive problems of AD: four are acetylcholinesterase inhibitors (tacrine, rivastigmine, galantamine and donepezil) and the other (memantine) is an NMDA receptor antagonist. The benefit from their use is small. No medication has been clearly shown to delay or halt the progression of the disease.

what is the best description for long-term potentiation (ltp) In neuroscience, long-term potentiation (LTP) is a persistent strengthening of synapses based on recent patterns of activity. These are patterns of synaptic activity that produce a long-lasting increase in signal transmission between two neurons. what is mean by the first mentioned science? It is the scientific study of the nervous system. regarding ltp; what is the earlier learning theory? The number of neurons in the adult brain (roughly 100 billion) did not increase significantly with age, memories were generally not the result of new neuron production, memories could form in the absence of new neurons. who discovered this? LTP was first observed by Terje Lømo who was this person? A Norwegian physiologist who specialized in neuroscience. what are the main branches of this science? Molecular neuroscience, Cellular neuroscience what is meant by the former one? A branch of neuroscience that observes concepts in molecular biology applied to the nervous systems of animals. is any disease observed in this regard? Neurodegenerative diseases like Alzheimer's, Parkinson's disease, Huntington's disease what are the possible causes of the first neurodegenerative disease? Abnormal amounts of proteins, amyloids and possibly tau proteins form in the brain. The resultant plaque disrupts normal functioning leading to a significant deficit of neurotransmitters, resulting in loss of brain function. what kind of protein is the mentioned one? The tau proteins  are a group of six highly soluble protein isoforms produced by alternative splicing from the gene "MAPT" (microtubule-associated protein tau). They have roles primarily in maintaining the stability of microtubules in axons and are abundant in the neurons of the central nervous system (CNS).

Alzheimer's disease [SEP] Medications
Glutamate is an excitatory neurotransmitter of the nervous system, although excessive amounts in the brain can lead to cell death through a process called excitotoxicity which consists of the overstimulation of glutamate receptors. Excitotoxicity occurs not only in Alzheimer's disease, but also in other neurological diseases such as Parkinson's disease and multiple sclerosis. Memantine is a noncompetitive NMDA receptor antagonist first used as an anti-influenza agent. It acts on the glutamatergic system by blocking NMDA receptors and inhibiting their overstimulation by glutamate. Memantine has been shown to have a small benefit in the treatment of moderate to severe Alzheimer's disease.
