Early Onset Familial Alzheimer's Disease (FAD) genetic link Age 30 to 60

Late Onset Diagnosed whena person has cognitive declineGenetic link suspected Emerging evidenceepigenetic mechanisms contribute to Alzheimer's disease~NIH 2012

1. Educate yourself about the disease2. Learn caregiving techniques. 3. Understand the experience of your loved one4. Avoid caregiver burnout5. Maintain your own physical and mental health. 6. Discuss the situation with family and friends. 7. Do cognitive stimulation activities with your loved

one. 8. Foster communication with physicians9. Take care of financial, legal and long-term care

planning issue10. Smile11. Think positive12. Reach out for care.

1.Increasing forgetfulness and mild confusion.

2.Inability to speak and write coherently

3.Impaired judgment and problem solving

Evidence indicates Use the sense of smell to determine

if someone may get Alzheimer’s disease

Use changes in sense of smell to begin treatments, instead of waiting until someone has issues learning and remembering

Determine if therapies are workingThe Journal of Neuroscience, Nov. 2, 2011 Case Western Reserve Medical School

Starts in the olfactory – loss of smell one of the first signs

Short-term memory fails when Alzheimer's disease first destroys nerve cells in the hippocampus

Language skills and judgment decline when neurons die in the cerebral cortex

1906Dr. Alois Alzheimer, German physicianPresented a case history of a 51-year-

old woman who suffered from mental illness

He identified through autopsy plaques and tangles in her brain

These plaques and tangles characterize Alzheimer's Disease

Integral membrane protein concentrated in the synapses of neurons.

Its primary function is not known, though it has been implicated as a regulator of synapse formation, neural plasticity and iron export
