Schizophrenia

Schizophrenia is a very severe mental disorder that disrupts a person’s everyday life. In earlier history, those suffering from Schizophrenia were thought to be possessed by demons. People were afraid of them, tormented them, and kept them away from society by locking them up. Just by reading that people used to think that people with Schizophrenia were possessed by demons, it is easy to tell that Schizophrenia is a very severe and serious disorder.

To this day, Schizophrenia affects over 2 million Americans which is about 1% of the U.S. population. People with Schizophrenia can no longer function normally because they are no longer in touch with reality. Schizophrenia makes it difficult to distinguish between what is real and unreal, think clearly, manage emotions, and relate to others. The five main symptoms of Schizophrenia are delusions, hallucinations, disorganized speech, disorganized behavior, and the so-called “negative” symptoms.

The symptoms vary from person to person and may be more severe in some than others. Delusions are very common in this disorder. They occur in about 90% of those affected. They can include delusions such as delusions of persecution where those affected think someone is out to get them, or delusions of grandeur where they think they are a grandiose figure such as God. Hallucinations are also common in people with Schizophrenia. They include hearing and seeing things that are not there. Auditory hallucinations are most common. Disorganized speech is when people say illogical things and speak incoherently. They may shift rapidly from topic to topic, make up words, or repeat the same things over and over. Disorganized behavior includes behaviors that appear bizarre and have no purpose, and inappropriate emotional response. The negative symptoms refers to absence of behaviors that a normal person should have. People with Schizophrenia lack emotional expression and interest in things that used to interest them.

What causes Schizophrenia is not 100% concluded although it has been shown that genes and environmental factors play a role in the cause of Schizophrenia. Schizophrenia strikes without regard to gender, race, social class or culture

 

Major Depressive Disorder

The exact cause for major depressive disorder is not known but according to research, it is believed that it is caused by chemical changes in the brain. It may be because of a problem with certain genes or by stressful events that occur suddenly. Depression also can be triggered in a person if it runs in the family.

Symptoms of Major depressive disorder according to WebMD are, fatigue or loss of energy almost every day, impaired concentration, insomnia or hypersomnia, significant weight loss or gain, and recurring thoughts of death or suicide.

            It has been shown that people who have relatives that have or have had depression have a high probability of having early-onset depression (before age 30).  WebMD also states that almost twice as many women than men have major depression. Hormonal changes for women during puberty, pregnancy, menopause, etc. increase the risk. On the contrary, older men with decreasing levels of the hormone testosterone have an increased risk for major depressive disorder. Studies have also shown that most people with depression have decreased activity in the left hemisphere and increased activity in the right.

            It has to be very hard to live with a disorder such as major depressive disorder. To feel sad and helpless every single day for weeks or months at a time has to be very difficult because people who are going through this feel as if life is worthless and has no meaning. They lose complete interest in what was once interesting and motivating for them.

 

Alzheimer's disease

Alzheimer’s disease is a devastating form of dementia. I can honestly say that it is a devastating disease. I have seen the effects it causes and they are horrible. It completely takes over a persons’ life. I have seen a close family member not remember people, become delusional, get lost in daily routes, and have trouble doing simple tasks.

          Alzheimer’s is an irreversible and progressive disease that slowly gets worse and worse. It affects a persons’ memory, thinking an behavior. Once it strikes, it gradually progresses into more serious memory loss, confusion, depression, hallucinations, delusions, and loss of appetite.

            According to an article, the causes of Alzheimer’s disease begin in the preclinical stage, where there are no symptoms but toxic changes begin to take place in the brain. A protein called amyloid starts accumulating in the brain and damages axons and dendrites.  These abnormal deposits form amyloid plaques and tau tangles which cause neurons to work less efficiently and with time they die. Soon the damage spreads to the hippocampus, which is important for forming memories. As neurons die, the damaged area begins to shrink and by the final stage the brain tissue has significantly shrunk.

            There are 3 stages in Alzheimer’s disease: mild, moderate, and severe. In the mild stage, symptoms include getting lost, taking longer to complete tasks, forgetting recent events, trouble solving problems, and mood changes. In the moderate stage, symptoms include changes in sleep patterns, delusions, hallucinations, poor judgment, and difficulty doing basic tasks. In the severe stage people with Alzheimer’s disease can no longer understand language, recognize family members, and can no longer care for themselves.

            It is heartbreaking to see how the gradual process of Alzheimer’s disease slowly takes over and destroys people’s lives. To go from a normal functioning person to not recognizing anyone and completely depending on others for their care is very distressing.

 

 

 

 

 

 

 

Post-Traumatic Stress Disorder

We have a hard time dealing with daily stressors such as exams and work and sometimes we feel like it’s too much and we can’t handle it. I know I have felt this way at times. These forms of stress might not be as hard to handle as the stress someone who has PTSD has to deal with. In earlier years, PTSD was referred to as “soldier’s heart” in the American Civil War, “combat fatigue” in World War I, “gross stress reaction” in World War II, “post-Vietnam syndrome” in the Vietnam War, and others such as “battle fatigue or shell shock.” Post-traumatic Stress Disorder is a type of anxiety disorder that can occur in people who have experienced terrifying unforgettable traumatic events or life threatening events.  Some events that may cause PTSD are war, rape, assault, car accidents, etc. Research has also shown that most PTSD victims have a smaller than average hippocampus. That would make people with a smaller hippocampus more vulnerable to PTSD.  People diagnosed with PTSD have symptoms for at least a month after the traumatic event and it can last up to years. Some of the symptoms according to an article, include reliving the event, avoidance of reminders of the events, and exaggerated arousal to many stimuli. I myself have been in a car accident which left me with some PTSD symptoms for a while. I was fearful of driving and would imagine at many times that cars were going to crash into me or that I would just somehow get into another accident. Although this wasn’t as severe as PTSD I can relate a little to these people and can imagine how hard it must be for them to deal with everyday stress and also deal with this disorder that haunts you everyday.
