With the arrival of lecanemab and donanemab, which remove causative substances and inhibit the progression of dementia, Alzheimer&#8217;s treatment has entered a phase where it can be cured, rather than just &#8220;slowing progression.&#8221; It is still in development and cannot be called a &#8220;dream new drug that can cure,&#8221; but it has a significant psychological effect.<\/p>\n\n\n\n<p>Excluding the two new drugs mentioned above, there are currently four types of medications approved for the treatment of Alzheimer&#8217;s in terms of medical fees.
