Hi, I am Dr. Michael Murray. Phosphatidylserine or PS for short is the major fatty substance in the human brain. It plays a major role in determining the integrity and fluidity of cell membranes. Without sufficient levels of PS, brain cells do not transmit the nerve impulse properly. Normally the brain can manufacture all of the PS it requires, but there is evidence that insufficient production in the elderly is linked to depression, poor memory, and impaired mental function. Good clinical results have been obtained in numerous double-blind studies with PS. The typical dosage is 300 mg daily

Glaucoma most often refers to the vision loss caused by increased intraocular pressure (IOP) as a result of greater production than outflow of the fluid of the eye (the aqueous humor). The normal intraocular pressure is about 10 to 21 mm Hg. In chronic glaucoma, the intraocular pressure is usually mildly to moderately elevated (22 to 40 mm Hg). In acute glaucoma, the intraocular pressure is greater than 40 mm Hg. Acute glaucoma is a medical emergency, fortunately it is the rarest form of glaucoma.
Chronic open-angle type glaucoma is by far the most common form. It accounts for about 70-75% of the approximately 3 million people in the United States who have glaucoma.
In some cases glaucoma develops in people with normal IOP. Referred to as low-tension glaucoma or normotensive glaucoma (NTG), this form accounts for approximately 25 to 30 percent of all glaucoma cases in the United States. NTG is more common in women than in men and affects adults averaging 60 years old. A common risk factor for NTG is low blood pressure.
Since many patients with glaucoma have no symptoms, it is important that regular eye exams be included in their annual checkup after the age of sixty. Glaucoma is a serious condition that requires strict attention.

Mind Your Ps and Qs
PQQ may be the perfect answer to preventing or reversing age-related mental decline.
kiwiPQQ (short for pyrroloquinoline quinone) is a vitamin-like compound found in plant foods that shows a wide range of benefits for brain function and energy production. Learn more about PQQ with the following Q&A.
What Exactly Does PQQ Do?
PQQ is an extremely potent antioxidant that is able to carry out the role of an antioxidant in the body more than 20,000 times—which is a rare thing. For example, other antioxidants, such as vitamin C, are only able to accomplish this “cycling” process about four times.
Are There Any Food Sources of PQQ?
PQQ has been found in all plant foods analyzed to date. Particularly PPQ-rich foods include parsley, green peppers, kiwi, papaya, and tofu. These foods contain 2–3 mcg of PQQ per 100 grams. Green tea provides about the same amount per 4-oz. serving. While these amounts appear to be sufficient in helping our cells carry out their basic functions, research indicates that boosting PQQ through supplementation can produce some amazing effects.
