Depression issues are hard to handle only by medication. There are various pharmaceutical companies in the world that are constantly researching on resolving depression issues through medications but there has not been any major breakthrough yet. Hence, AstraZeneca one of the leading pharmaceutical companies in the world has decided to tread on a different path to achieve success and to do that they have gone for partnership with Depression and Bipolar Support Alliance (DBSA) that works for the welfare of patients suffering from bipolar depression and major depressive disorders. Together they have launched their new campaign known as Speak and Be Heard Living with Depression.

Stroke is a syndrome characterized by the acute onset of a neurologic deficit that persists for at least 24 hours, reflects focal involvement of the central nervous system, and is the result of a disturbance of the cerebral circulation. Stroke is the third most common cause of death in the United States and the most common disabling neurologic disorder.

Stroke incidence is defined by the number of first cases of stroke over a defined time interval in a defined population, whereas stroke prevalence measures the total number of cases, new and old, at a particular time also in a defined population. Stroke incidence estimations depend on whether the data are gathered clinically, by CT, or at autopsy and whether the study is hospital or population based.

Any infection of the nervous system is potentially serious and, not uncommonly, may prove fatal. Major infections include tetanus, encephalitis, meningitis, poliomyelitis, and rabies. Tetanus, or lockjaw, is caused by the bacterium Clostridium tetani, an inhabitant of soil and feces- hence the danger of dirty wounds. Muscle spasms and convulsions highlight the infection. Unless tetanus antitoxin is given immediately, the outlook is grim; even with only a 24 hour delay a person's chances are no better than 50-50. Actually, no one need die of tetanus: vaccination is 100% effective.

Poliomyelitis is an acute viral infection of the central nervous system. Somewhat contrary to popular belief, relatively few of those affected develop significant signs and symptoms. These include, in a full blown infection, fever, headache, stiffness, and paralysis. Less than one quarter of those who develop paralysis sustain permanent disability. Death can occur as a result of respiratory failure. Vaccination has proved extremely effective in the prevention of polio, and the oral vaccine is recommended for all infants and children.

The human body contains a dozen billion nerve cells (neurons) interwoven into what we call the brain and spinal cord. The basic unit of the nervous system is the  neuron, which consists of a cell body and branched extensions, or processes. Dendrites are those processes conducting nerve (electrical) impulses to the cell body, and axons are those processes conducting nerve impulses away from it. Sensory neurons conduct nerve impulses to or toward the central nervous system; motor neurons conduct nerve impulses to the muscles, glands, and organs; and connector neurons conduct impulses from sensory to motor neurons.

Whereas the sensory neuron typically has long dendrites and a short axon, the motor neuron has short dendrit and a long axon; connective neurons generally have short processes. The junction between the terminal endings of the axon of one neuron and the dendrites of another is referred to as a synapse.
