![]() How Does Molecular Imaging Help People with Brain Disorders? stroke and transient ischemic attack (TIA).mental disorders such as schizophrenia and drug and alcohol addiction.neurodegenerative diseases, such as Parkinson’s disease, amyotrophic lateral sclerosis (ALS), Huntington’s disease, Alzheimer’s disease and other forms of dementia.Researchers are using molecular imaging to gain a better understanding of the brain and to develop treatments for: In Alzheimer’s disease and other types of dementia, large numbers of neurons stop functioning, lose connections with other neurons and die.īoth malignant and benign tumors also affect the brain, destroying brain cells and causing pressure on other parts of the brain and increased pressure within the skull. Surges in electrical signals inside the brain may cause recurring seizures, or epilepsy.īrain cells deprived of oxygenated blood during a stroke die, causing permanent damage. ![]() When electrical signals in the areas of the brain that control movement are abnormal, tremors may occur. For example, depression is associated with either an excess or a shortage of neurotransmitters, such as serotonin, noradrenaline and glutamate. Many brain disorders, such as Parkinson’s disease and depression, are linked to a disruption in brain circuitry. When this process does not work properly, mental illness can occur. During the binding process the neurotransmitter’s message is passed on.
