Depression The Role of Depression and Anxiety in Substance Use Although it is common for teens to experience frequent mood swings, your teen may be experiencing a form of depression if clusters of the following thoughts, feelings, and behaviors persist for two weeks or longer. Prompt identification and treatment of depression can reduce its durations and severity. Look for the following signs: (Adapted from U.S. KNOW YOUR FAMILY HISTORY of mental health issues. Chapter 2—How Stimulants Affect the Brain and Behavior - Treatment for Stimulant Use Disorders - NCBI Bookshelf Alcoholism and Alcohol Abuse: Signs, Symptoms, and Help for Drinking Problems Understanding alcoholism and alcohol abuse Alcoholism and alcohol abuse are due to many interconnected factors, including genetics, how you were raised, your social environment, and your emotional health. Some racial groups, such as American Indians and Native Alaskans, are more at risk than others of developing alcohol addiction. People who have a family history of alcoholism or who associate closely with heavy drinkers are more likely to develop drinking problems. Finally, those who suffer from a mental health problem such as anxiety, depression, or bipolar disorder are also particularly at risk, because alcohol may be used to self-medicate. Do you have a drinking problem? You may have a drinking problem if you... Feel guilty or ashamed about your drinking. Since drinking is so common in many cultures and the effects vary so widely from person to person, it’s not always easy to figure out where the line is between social drinking and problem drinking.

The results of the analysis showed that when both of the above factors combined, alcohol abuse is the most dangerous or damaging, only then heroin and then cocaine. The paper was written by Professor Nutt of Imperial College London, and the Independent Science Committee on Drugs, Dr. The new assessment uses nine categories of danger to self and seven categories of hazards to the community as a whole variety of individuals. The categories “danger to self” itself covers death or mortality, poor health, decreased intellect, loss of friendships and injury. The categories “danger to others” include crime, environmental damage, family conflict and decline in community unity.
Why People with Down Syndrome Invariably Develop Alzheimer’s Disease A new study by researchers at Sanford-Burnham Medical Research Institute reveals the process that leads to changes in the brains of individuals with Down syndrome—the same changes that cause dementia in Alzheimer’s patients. The findings, published in Cell Reports, have important implications for the development of treatments that can prevent damage in neuronal connectivity and brain function in Down syndrome and other neurodevelopmental and neurodegenerative conditions, including Alzheimer’s disease. Down syndrome is characterized by an extra copy of chromosome 21 and is the most common chromosome abnormality in humans. It occurs in about one per 700 babies in the United States, and is associated with a mild to moderate intellectual disability. Amyloid plaques are found in the brains of people with Down syndrome and Alzheimer’s disease. Beta-Amyloid, Plaques and Dementia Xu’s team found that SNX27 regulates beta-amyloid generation.

Alcohol Abuse Statistics - Facts About Alcoholism & Addiction - Drug-Free World Alcohol kills more teenagers than all other drugs combined. It is a factor in the three leading causes of death among 15- to 24-year-olds: accidents, homicides and suicides. Youth who drink are 7.5 times more likely to use other illegal drugs and fifty times more likely to use cocaine than young people who never drink. One survey found that 32% of the heavy drinkers over 12 were also illegal drug users. Quotes About Science Neurology (1 quote) “Individuality is deeply imbued in us from the very start, at the neuronal level. Even at a motor level, researchers have shown, an infant does not follow a set pattern of learning to walk or how to reach for something. Each baby experiments with different ways of reaching for objects and over the course of several months discovers or selects his own motor solutions. When we try to envisage the neural basis of such individual learning, we might imagine a "population" of movements (and their neural correlates) being strengthened or pruned away by experience. Similar considerations arise with regard to recover and rehabilitation after strokes and other injuries. And in its broadest sense, neural Darwinism implies that we are destined, whether we wish it or not, to a life of particularity and self-development, to make our own individual paths through life
How Does Alcohol Affect the Brain? Effects of Alcohol on Teenagers - Drug-Free World Photo credits: Stockxpert A young person’s body cannot cope with alcohol the same way an adult’s can. Drinking is more harmful to teens than adults because their brains are still developing throughout adolescence and well into young adulthood. According to research, young people who begin drinking before age 15 are four times more likely to develop alcohol dependence than those who begin drinking at age 21. For some teens, like Samantha, drinking seems to be a solution to problems they don’t want to face. “When I was 13, friends would make fun of me if I didn’t have a drink. “I went out less and less so started losing friends and the more lonely I got, the more I drank. “I was violent and out of control. Kicked out of her home at age 16, she was homeless and started begging for money to buy drinks. “...I was only 16 but my liver was badly damaged and I was close to killing myself from everything I was drinking.”
How Our Brains Overrule Our Senses - 12/07/2015 Is it a duck or a rabbit? The same sensory stimulus can produce different perceptions. Jastrow, J. (1899). The mind's eye. Popular Science Monthly, 54, 299-312. Scientists have long known that when sounds are faint or objects are seen through fog in the distance, repetition of these weak or ambiguous sensory “inputs” can result in different perceptions inside the same brain. “In everyday life, we experience weak stimuli all the time,” says senior researcher Daniel O’Connor, Ph.D., assistant professor of neuroscience at the Johns Hopkins University School of Medicine. To find out, O’Connor and his team used a simple model: the gentle tickling of a single mouse whisker, a sensory organ common to many animals. To get at the answer, the researchers had to train the mice to indicate when they felt tickled. “The cortex’s response to exactly the same stimulus wasn’t always the same, but it correlated with the animals’ licking,” says O’Connor.
