[Medical treatment of Alzheimer's disease].

OBJECTIVE

To review the drugs commercially available at present and in the near future in relation to the evolution of Alzheimer disease, bearing in mind the possible psychiatric disorders which may be associated with the disease.

DEVELOPMENT: The therapeutic approach is planned according to the different phases of the disease. In the preclinical phase, anti-inflammatory drugs and estrogens in post-menopausal women have been effective. In the initial phase current recognition therapy is directed basically towards correcting the break-down of acetylcholine (tacrine, donepezil, SB202026, SDZ ENA 713). For depressive symptoms serotonin levels are corrected using selective inhibitors of serotonin uptake.

CONCLUSIONS

Drug treatment should be considered with the association of drugs which activate the malfunctioning circuits and/or pathways. It would also be useful to design clinical studies using pharmacological combinations of cholinergic agonists, estrogens, anti-inflammatory drugs, seligiline and/or new anti-cholinesterase drugs amongst others.
