• It was named after the German physician ;
Dr. Alois Alzheimer .

3. • In 1906 , he presented a case history
before a medical meeting of a 51-year-old
woman who suffered from a rare brain
disorder. A brain autopsy identified the
plaques and tangles that today
characterize Alzheimer's disease.

6. Alzheimer's disease is a progressive,
degenerative disorder that attacks the
brain's nerve cells, or neurons, resulting in
loss of memory, thinking and language
skills, and behavioral changes.

7. Types of Alzheimer’s
There are 2 types of Alzheimer’s :
Familial Alzheimer’s Disease
(FAD)
between age 30 – 60
Sporadic Alzheimer’s Disease
(SAD)
at age over 65

8. How does Alzheimer’s take place !!
Two types of abnormal lesions clog the
brains of individuals with Alzheimer's
disease:
Beta-amyloid plaques
Neurofibillary tangles

11. How are plaques and tangles
are formed !!

14. How do they work !!

15. APP ⇒ Aß42 ⇒ fibrillar Aß and
oligomers ⇒ amyloid plaques
amyloid plaques ⇒ inflammation and
NFTs ⇒ neuron death and synapse loss

27. Diagnosis of AD
• Taking complete medical history .
• Conducting lab autopsy (which
pathologists look for the disease's
characteristic plaques and tangles in brain
tissue) .
• Neuro-psychological tests .

28. What we find is ….

29. Factors increasing chance of
having Alzheimer’s disease :
1-Age>65 years . More than
85 years increases risk to 50% .
2-Family history .
3-Genes .
Head injury .
5- Brain health is
connected to
heart health . So high blood pressure ,
high cholesterol and stroke can increase
risk of having Alzheimer’s disease .

30. Treatment of AD
• Till now there is NO cure for Alzheimer’s.
• But the (FDA) has approved several
medications for the treatment of
Alzheimer’s disease which may help slow
progression of symptoms and improve
quality of life.
