The goal of this thesis was to show that brain perfusion SPECT can help to clarify important issues regarding the prodromal MCI stage of AD and relapsing NMO. Specifically‚ this thesis shows: 1. That based on recently published literature‚ brain perfusion SPECT is a valid biomarker of neuronal injury in MCI due to AD in both clinical and research settings‚ equivalent to FDG-PET but less expensive and more accessible worldwide (Chapter 2). 2. That brain perfusion SPECT combined with graph theoretical

The Ten Principles and Brain Development At birth there are about 100 billion brain cells produced and they are beginning to connect with each other. At the first week of age‚ brain development starts with conception. It is important to reach the age of an infant and practice the ten principals. In the early years‚ young brains produce almost twice as many synapses as they will need. By age two‚ the number of synapses a toddler has is similar to that of an adult. By three the child has twice

Theory of brain specialization suggests that different parts of the brain control specific tasks. For example‚ we know that the left hemisphere of the brain is responsible for language. Through these findings‚ Gardner was able to develop his own theory of multiple intelligences (MI Theory) which defends the idea that different regions of the brain are in control of different aspects of intelligence or‚ more correctly‚ different intelligences all together. To defend his theory of multiple intelligences

neurotransmitter levels in the brain‚ and specifically levels of dopamine and serotonin. As these chemicals are both involved in the brain reward ‘circuits’ (e.g. the mesolimbic pathway) drugs produce feeling of ‘euphoria’. Drugs can affect Elizabeth’s brain in two ways‚ as a depressant or a stimulant to normal activity and as a result Elizabeth’s mood and behaviour is affected. Elizabeth’s drug addiction can be explained by a significant change to the neurotransmitter action in the brain. Some drugs slow down

Alpha waves – have frequency of (8-13 Hz). Waves are regular and rhythmic‚ are synchronous and have low amplitude. They signify an awake but calm brain. Beta waves – have frequency of (14-30 Hz). Waves are rhythmic but not so regular‚ and have higher frequencies. They signify wakefulness and alertness.

What is Brain Chemistry? Brain chemistry or neurochemistry is the complex system which allows the brain to function with the use of chemicals known as neurotransmitters which move information around in the brain. Every person’s brain chemistry is slightly different‚ and a number of things can play a role in the levels of various neurotransmitters in the brain‚ and how those chemicals affect the brain’s function. It is believed that difference in brain chemistry may explain a variety of behavioral
