Phosphatidylserine (PS)
Phosphatidylserine is one of the many substances involved in the structure and maintenance of cell membranes. Commercially made from soybeans it was asserted by the US Food and Drug Administration in May 2003 that "consumption of phosphatidylserine may reduce the risk of dementia in the elderly" and further, "consumption of phosphatidylserine may reduce the risk of cognitive dysfunction in the elderly". Numerous studies back this up with evidence showing patients who took Phosphatidylserine orally showed significant improvement in their symptoms.

Ginkgo Biloba
Ginkgo Biloba is an extract from the Maidenhair Tree that only grows in a small part of China. It contains a special extract called EGb 761 that has been shown at the Psychiatry Department at the National Medical University, Kyiv in the Ukraine to have demonstrated significant improvements in cognitive functioning and behavioral symptoms in patients suffering from Alzheimer’s. Further studies have also concluded that the Ginkgo biloba special extract EGb 761 seems to produce neuro-protective effects in neuro-degenerative diseases like Alzheimer’s.

Vinpocetine
Vinpocetine is an extract from the periwinkle plant (vinca minor), a herb that is known to help improve the flow of oxygen and blood, particularly in cerebral veins. Studies have reported the enhanced cerebral blood-flow particularly helps alleviate neuro-disorders like Alzheimer’s.

Lemon Balm
Lemon Balm, a fairly tall herb, also native to Southern Europe and the Mediterranean region and often used in teas, is another natural remedy that is also helpful for Alzheimer’s sufferers. A study at the Roozbeh Psychiatric Hospital at the Tehran University of Medical Sciences in Iran has shown that Melissa officinalis (an extract from the lemon balm plant) can help in the management of mild to moderate Alzheimer’s disease. Further studies have shown it can also improve quality of life for patients, which can only be beneficial to them and their families.

Music Therapy
Several studies have demonstrated the benefits of music therapy in Alzheimer's patients. In a study of 32 apathetic participants with moderate to severe dementia, 69% of the group demonstrated a positive response to live music, with prerecorded music being less beneficial.
However, prerecorded music can be of great benefit as other studies have shown. A significant decrease in aggressive behavior during bathing episodes was noted when music was played, 12 out of 15 Alzheimer's patients demonstrated a decrease in aggressive behavior.
In another study involving 28 participants, an increase in positive social behavior and a decrease in negative behavior were observed when music was played.
The School of Music at the University of Western Australia has reported a traceable development in the alertness of Alzheimer's patients in a group-singing project.

Acetyl-l-carnitine
Commonly used to help angina, heart failure and other heart conditions, Carnitine is a vitamin-like substance taken orally. A special form of carnitine, acetyl-L-carnitine, has been extensively tested for the treatment of degenerative diseases like Alzheimer’s and dementia. Beneficial effects have been noted on both the clinical scales and the psychometric tests, showing that consumption of Acetyl-L-carnitine has been shown to contain neuro-biological properties – basically this means it can slow down the onset of Alzheimer’s disease.

Choline
A naturally occurring compound, Choline is part of the B Vitamin group and has been shown to consistently help slow the progress of Alzheimer's and improve neurol functioning of suffers.

Sage
Sage is a low-growing, fairly small evergreen shrub with grey colored leaves, woody stems and purple flowers. Native to the Mediterranean, sage is often cultivated to add flavour to food and for its medicinal properties. Sage has been used as herb for many centuries, because it contains a number of helpful properties: it is an antifungal, antimicrobial, antioxidant and antiseptic. It can also help reduce inflammation and be used as a laxative and a stimulant to help with digestion. For Alzheimer’s, sage is highly beneficial, and in studies has been shown to stimulate cognitive functions of patients.

Huperzine A
Another organic extract, Huperzine A has been used in China for centuries for the treatment of swelling, fever and blood disorders. Recent trials have also indicated it may be useful for treating patients suffering from neuro-degenerative diseases like Alzheimer’s disease.

Alpha-tocopherol (Vitamin E)
In the US, the Department of Neurology at Columbia University College of Physicians and Surgeons, New York has explored the claim that vitamins, particularly Vitamin E can increase the levels of brain and therefore slow down the progress of Alzheimer's disease. Their studies proved that taking Vitamin supplements does indeed slow the development of the Alzheimer’s.
