Neurodegenerative diseases is a common cause of dementia which means that the brain cells known at the neurons either are degenerating therefore the neuron die off quicker than that of the neurons of a normal aging processes. This will lead to a more decline in the persons mental health such as memory‚ language and sometimes their physical abilities all depending on which area of the brain is infected. These neurodegenerative diseases are known to us as Alzheimer’s‚ fronto-temporal dementia‚

Reserpine. Pharmacology: Most often used to treat mild to moderate hypertension. Rarely used as an antipsychotic. Mode of action: Reserpine works by irreversibly blocking the vesicular monoamine transporter (VMAT). This transporter normally transports dopamine (DA)‚ 5-HT (serotonin)‚ and norepinephrine (NE) from the cytoplasm to the vesicle in the presynaptic neuron. Because these neurotransmitters are not packaged‚ they are degraded quickly by monoamine oxidases (MAOs). 4. Inhibition of synthesis of

The PFC is involved in judgment‚ impulse control‚ planning‚ follow through‚ decision making‚ and paying attention. This type is often seen with ADD and ADHD and is more common in males.

The debate over antidepressants has waged on for over more than half a century. Two heads of the Department of Psychiatry in Washington University discovered that depression was just as much biological as it was physiological meaning that people with depression had an abnormal chemical make-up in the brain. This discovery increased the demand for research on methods to alter this abnormality effectively and efficiently. Thus antidepressants were created‚ sparking a psychiatric revolution.

part of the dopamine pathway which is a potential transport highway for psychoactive drugs. The hypothalamus is at the base of the brain and serves as liaison between the brain and pituitary gland. The pituitary hormonal output is involved in behaviors such as feeding and temperature regulation. The limbic system affects emotion‚ location memory‚ and physical activity. Along the brain stem are the medulla‚ midbrain‚ and pons from which contain the bulk of neurons that create dopamine‚ norepinephrine
