MENTAL alertness/clarity/cognition

Choline, ashwagandha, phosphatidyl-serine (PS), grape seed, vinpocetine, ginger and rosemary are readily available supplements/foods/herbs that preserve and restore brain function.  Ashwagandha significantly helps Alzheimer's by halting/repairing brain cell damage, regenerates axons and dendrites, + reconstructs pre and post neuron synapses.  PS improves cognition/socialization/motivation/behavior due to aging by boosting brain glucose metabolism and acetyl-choline.  Red wine and grape seeds contain proanthocyanidins which appear to be 20-50% more beneficial than vitamin E or vitamin C and seem to prevent DNA oxidative damage from beta-amyloid (Abeta) toxic protein and neuroprotective to13 proteins.  Vinpocetine may help cell electrical conductivity and cerebral blood flow.
In newborns with brain trauma, vinpocetine reduced/eradicated seizures and high brain blood pressure. 
In the body pregnenolone hormone (from wild yams)  is converted to DHEA, estrogen, progesterone, or testosterone as needed. Pregnenolone directly influences brain acetyl-choline release, sleep-wakefulness cycle, and neurogenesis (new nerve growth). Ginger and rosemary are anti-inflammatory. 10/2005

Ginkgo Biloba L. Family: Ginkgo-aceae - http://www.factsandcomparisons.com/common/pdf/RNPLL_websample_monogr.pdf - "Ameta-analysis of 11 placebo-controlled, randomized, double-blind studies,concluded that GBE 150 mg daily was superior to placebo inpatients with cerebro-vascular insufficiency.38... 
In elderly men with slight age-related memory loss, ginkgo supplementation reduced the time required to process visual information.52 Effects of GBE on event-related potentials in 48 patients with age-associated memory impairment have been studied.53 Improvement in memory, as measured by a series of psychological tests, in 8 patients (average age, 32 years) was found 1 hour after administration of GBE 600 mg versus placebo, again confirming the plantís effectiveness.7"  http://www.factsandcomparisons.com/review-of-natural-products-loose-leaf.aspx

Scripture

 
The Curses of Disobedience (until repentance) - deuteronomy/28-28.htm
27The LORD will afflict you with the boils of Egypt, with tumors and scabs and itch from which you cannot be cured.

28
The LORD will afflict you with madness, blindness, and confusion of mind,

29
so that at noon you will grope about like a blind man in the darkness. You will not prosper in your ways.
Day after day you will be oppressed and plundered, with no one to save you.
Daniel 1:20 NKJV In all matters of wisdom and understanding about which the king examined them, he found them 10X better than all...who were in all his realm. (vegetarian diet)
Enoch 2 - http://www.ccel.org/c/charles/otpseudepig/enoch/ENOCH_2.HTM  - Chapter 48: 1 In that place I saw the fountain of righteousness, which was inexhaustible. Around it were many fountains of wisdom. All the thirsty drank of them, and were filled with wisdom.

Hagin, Kenneth E  How You Can Be Led by the Spirit of God Chapter12 Effects of the Spirit's Indwelling shares "Every day as I walked to school I would confess, 'In Him was life and the life was the light of men.  That life is in me...
That life is the light. It is the development of me.  It is developing my spirit.  It is developing my mentality. 
I have God in me.  I have God's wisdom in me.  I have God's life in me.  That life of God in my spirit dominated me. 
I purpose in my heart to walk in the light of life'...By receiving eternal life into my spirit and getting my mind renewed with the Word, my mentality was increased from 30 to 60%." www.rhema.org
Hayes, Norvel Know Your Enemy  www.nhm.cc Chapter 4 The Devil Must Obey You  "I wanted God to touch my mind, to help me think straight.  3 years I prayed that prayer. 3 years...I let the Word (of God) go into my mind and into my spirit.  I have not had a confused day in years... When the devil comes to attempt to mess up your mind, just say, 'No, you don't'...with authority...Take authority over disease and stop it yourself."

Paul shares how the Limbic system's thalmus only obeys your own voice.  Beware what you speak! 
When Paul became teachable, God revealed how to rewire the brain. 
One significant method is to read the Bible out LOUD (especially the red lettered words of God/Jesus.)
The brain's
amygdale has a major role in one's emotional development.  It can be rewired

Within God's parameters we can call into being health, length of life, longevity, mental clarity, etc.
Led by the Spirit by Elaine Tavolacci - 5/21/2014 - "As you allow My word to become part of you, your mind will be renewed. You will no longer desire to submit to the things of the carnal nature. The temptations of this world will grow dim as you hunger for spiritual realities.  The more that you spend time in My word and in My presence, you will find that hearing My voice will come with ease. Pray in the spirit often to build yourself up in your most holy faith and as you do, you will become more attuned to My ways.  Soon you will find that as you continue to persevere, you will begin to be led by My Spirit. I will release discernment to see into the dark places. You will begin to discern the motives and intentions of the heart. You will understand My word with more clarity and insight." -
