Abstract

Neuropsychological studies of schizophrenia typically apply a small number of tests to a large group of patients. This approach has at least two drawbacks:

1. The heterogeneity of the condition will lead to group means which may not reflect the behaviour of any individual.
2. It is difficult to infer the nature of the underlying cognitive impairments from a small number of tests, since good performance on a particular test depends on many different cognitive processes. In these circumstances it is more appropriate to apply the methods of cognitive neuropsychology where a large number of tests are used on a single case. This approach has proved fruitful in the study of neurological patients.

Paranoid Schizophrenia

Paranoid schizophrenia is the most common type of schizophrenia in most parts of the world. The clinical picture is dominated by relatively stable, often paranoid, delusions, usually accompanied by hallucinations, particularly of the auditory variety, and perceptual disturbances. Disturbances of affect, volition, and speech, and catatonic symptoms, are not prominent.

Examples of the most common paranoid symptoms are:

delusions of persecution, reference, exalted birth, special mission, bodily change, or jealousy;
hallucinatory voices that threaten the patient or give commands, or auditory hallucinations without verbal form, such as whistling, humming, or laughing;
hallucinations of smell or taste, or of sexual or other bodily sensations; visual hallucinations may occur but are rarely predominant.

Thought disorder may be obvious in acute states, but if so it does not prevent the typical delusions or hallulcinations from being described clearly. Affect is usually less blunted than in other varieties of schizophrenia, but a minor degree of incongruity is common, as are mood disturbances such as irritability, sudden anger, fearfulness, and suspicion. "Negative" symptoms such as blunting of affect and impaired volition are often present but do not dominate the clinical picture.
The course of paranoid schizophrenia may be episodic, with partial or complete remissions, or chronic. In chronic cases, the florid symptoms persist over years and it is difficult to distinguish discrete episodes. The onset tends to be later than in the hebephrenic and catatonic forms.

What is depression?





We all go through ups and downs in our mood. Sadness is a normal reaction to life’s struggles, setbacks, and disappointments. Many people use the word “depression” to explain these kinds of feelings, but depression is much more than just sadness.

Some people describe depression as “living in a black hole” or having a feeling of impending doom. However, some depressed people don't feel sad at all—they may feel lifeless, empty, and apathetic, or men in particular may even feel angry, aggressive, and restless.

Whatever the symptoms, depression is different from normal sadness in that it engulfs your day-to-day life, interfering with your ability to work, study, eat, sleep, and have fun. The feelings of helplessness, hopelessness, and worthlessness are intense and unrelenting, with little, if any, relief.

Are you depressed?

If you identify with several of the following signs and symptoms, and they just won’t go away, you may be suffering from clinical depression.


* you can’t sleep or you sleep too much
*
* you can’t concentrate or find that previously easy tasks are now difficult
*
* you feel hopeless and helpless
*
* you can’t control your negative thoughts, no matter how much you try
*
* you have lost your appetite or you can’t stop eating
*
* you are much more irritable, short-tempered, or aggressive than usual
*
* you’re consuming more alcohol than normal or engaging in other reckless behavior
*
* you have thoughts that life is not worth living (Seek help immediately if this is the case)

Signs and symptoms of depression

Depression varies from person to person, but there are some common signs and symptoms. It’s important to remember that these symptoms can be part of life’s normal lows. But the more symptoms you have, the stronger they are, and the longer they’ve lasted—the more likely it is that you’re dealing with depression. When these symptoms are overwhelming and disabling, that's when it's time to seek help.

Common signs and symptoms of depression

Feelings of helplessness and hopelessness. A bleak outlook—nothing will ever get better and there’s nothing you can do to improve your situation.
Loss of interest in daily activities. No interest in former hobbies, pastimes, social activities, or sex. You’ve lost your ability to feel joy and pleasure.
Appetite or weight changes. Significant weight loss or weight gain—a change of more than 5% of body weight in a month.
Sleep changes. Either insomnia, especially waking in the early hours of the morning, or oversleeping (also known as hypersomnia).

Anger or irritability. Feeling agitated, restless, or even violent. Your tolerance level is low, your temper short, and everything and everyone gets on your nerves.
Loss of energy. Feeling fatigued, sluggish, and physically drained. Your whole body may feel heavy, and even small tasks are exhausting or take longer to complete.
Self-loathing. Strong feelings of worthlessness or guilt. You harshly criticize yourself for perceived faults and mistakes.
Reckless behavior. You engage in escapist behavior such as substance abuse, compulsive gambling, reckless driving, or dangerous sports.
Concentration problems. Trouble focusing, making decisions, or remembering things.
Unexplained aches and pains. An increase in physical complaints such as headaches, back pain, aching muscles, and stomach pain.

Depression can change or distort the way you see yourself, your life, and those around you.

People who have depression usually see everything with a more negative attitude, unable to imagine that any problem or situation can be solved in a positive way.

Symptoms of depression can include:

1. Agitation, restlessness, and irritability

2. Dramatic change in appetite, often with weight gain or loss

3. Very difficult to concentrate

4. Fatigue and lack of energy

5. Feelings of hopelessness and helplessness

6. Feelings of worthlessness, self-hate, and guilt

7. Becoming withdrawn or isolated

8. Loss of interest or pleasure in activities that were once enjoyed

9. Thoughts of death or suicide

10. Trouble sleeping or excessive sleeping

Depression can appear as anger and discouragement, rather than feelings of sadness.
If depression is very severe, there may also be psychotic symptoms, such as hallucinations and delusions.

Depression often looks different in men and women, and in young people and older adults. An awareness of these differences helps ensure that the problem is recognized and treated.

Depression in men

Depression is a loaded word in our culture. Many associate it, however wrongly, with a sign of weakness and excessive emotion. This is especially true with men. Depressed men are less likely than women to acknowledge feelings of self-loathing and hopelessness. Instead, they tend to complain about fatigue, irritability, sleep problems, and loss of interest in work and hobbies. Other signs and symptoms of depression in men include anger, aggression, violence, reckless behavior, and substance abuse. Even though depression rates for women are twice as high as those in men, men are a higher suicide risk, especially older men.

Depression in women

Rates of depression in women are twice as high as they are in men. This is due in part to hormonal factors, particularly when it comes to premenstrual syndrome (PMS), premenstrual dysphoric disorder (PMDD), postpartum depression, and perimenopausal depression. As for signs and symptoms, women are more likely than men to experience pronounced feelings of guilt, sleep excessively, overeat, and gain weight. Women are also more likely to suffer from seasonal affective disorder.

Depression in teens

While some depressed teens appear sad, others do not. In fact, irritability—rather than depression—is frequently the predominant symptom in depressed adolescents and teens. A depressed teenager may be hostile, grumpy, or easily lose his or her temper. Unexplained aches and pains are also common symptoms of depression in young people.

Left untreated, teen depression can lead to problems at home and school, drug abuse, self-loathing—even irreversible tragedy such as homicidal violence or suicide. But with help, teenage depression is highly treatable.

Depression in older adults

The difficult changes that many older adults face—such as bereavement, loss of independence, and health problems—can lead to depression, especially in those without a strong support system. However, depression is not a normal part of aging. Older adults tend to complain more about the physical rather than the emotional signs and symptoms of depression, and so the problem often goes unrecognized. Depression in older adults is associated with poor health, a high mortality rate, and an increased risk of suicide, so diagnosis and treatment are extremely important.

Postpartum Depression

Many new mothers suffer from some fleeting form of the “baby blues.” Postpartum depression, in contrast, is a longer lasting and more serious depression triggered, in part, by hormonal changes associated with having a baby. Postpartum depression usually develops soon after delivery, but any depression that occurs within six months of childbirth may be postpartum depression.
