Suspected Causes of Depression

Many potential causes of depression have been identified on the basis of research and keen observation. Various of these factors can interact and summate as they determine the course and severity of depressive episodes.

The following is a brief summary of possible causes:

Genetic factors have been implicated by researchers who study the extended families of depressed individuals and find that relatives have a significantly higher incidence of depression than the general population. Closer relatives of depressed persons have higher rates of depression than do distant relatives.

In twin studies identical twins have a much higher chance of both suffering from depression than do fraternal (nonidentical) twins. These kinds of studies could be taken as evidence for the learning of depressed behavior in families as a result of similar experiences, and learning can be an important factor. Adoption studies have also suggest that genetics can play a significant role in the development of depression.

Biochemical factors may also be involved in depression. Neurotransmitters are molecules that move between the neurons (special nervous system cells in the brain) allowing neuro-impulses to travel from one cell to the next. The search is not over, but so far, two specific neurotransmitters have been found to occur at low levels in depressed individuals. It has also possible that these neurotransmitters could be present in sufficient quantity, but may not used effectively by the brain. These neurotransmitters are norepinephrine and serotonin. Anti-depressant medications are known to increase the availability of these brain chemicals and/or to improve the way the brain uses them, thereby relieving depression.

Hormonal factors may also be involved in depression. It has been found that people who are depressed frequently show elevated levels of cortisol. Cortisol is a hormone released by the adrenal glands when individuals are under stress. Stressful events are often found to have preceded episodes of depression. High levels of another hormone named melatonin have also been implicated in depression. It is thought that the lack of sun associated with winter months may cause a build up of melatonin and produce the depression that is called seasonal affective disorder.

Psychological theories have identified many life events that predispose individuals to depression. Psychodynamic theorists have noted that the death or loss of a loved one early in life increases the likelihood of depression for the person experiencing the loss. The separation of children under six from their mothers has been found to lead to a form of child depression (anaclitic depression). These findings also hold for infant monkeys separated from their mothers. It appears that maintaining early emotional attachments with caretakers is very important to mental health of children and the adults that they become.

Behaviorists have observed that depressed individuals have often lost a significant proportion of the rewarding people, places, things, or abilities that they have customarily enjoyed in life. In some individuals a loss of important sources of rewards are thought to precipitate a downward spiral of depression in which these people do fewer things and therefore obtain even fewer rewards in their lives. Also, studies have demonstrated a behavioral contagion effect in which non-depressed people were exposed to other individuals who acted depressed. The findings were that some of those who were simply exposed to a depressed person began to feel depressed themselves.

Cognitive factors refer to a persons beliefs, attitudes and ways of thinking about the world. Cognitive-behavioral research has found that feelings of helplessness accompanying depressed behavior can be produced by repeatedly experiencing painful events over which the individual has no control. More recent changes to this theory note that a perceived lack of control over such painful events is more important than the actual control which is available.

Other psychologists have examined cognitive factors that can lead to depression. For example people can learn to think negatively about their past, present and future. They can also magnify various minor problems and minimize the good things in their lives. Depressed people also frequently have automatic thoughts which they think in a “reflexive”-like and uncritical way. Such thoughts might include things like: "I certainly am damaged goods", “I’ll never amount to anything”, I'm the biggest screw-up on earth", or "I've got so many problems I just can't take it anymore."

It is good that you have taken the time to become familiar with some of the likely factors that may predispose people to periods of depression. Knowing your risk factors could help you to lower some of them. Perhaps you could share this information with your loved ones. Knowing our risk factors can help us all to be more alert for early indications of depression and to seek professional help early.

As always, prevention and early treatment are the best approaches.

Preventing Depression in Children and Adolescents

Preventing Depression in Children and Adolescents

The symptoms of depression are likely to show themselves in different ways, depending upon the age of the child.

Infants may show listlessness, social unresponsiveness, and slowed physical development. Children up to about 2 yrs. of age are more likely to show little curiosity and interest in play. They may be clingy, fearful, have nightmares and night terrors and show an increase in oppositional and uncooperative behavior.

Between three and five years of age children may show sadness, tiredness, slow movement poor appetite and weight loss. They may also show withdrawal, apathy, irritability and anger. Some children may begin to express thoughts of suicide.

From 6 to 12 years depressed behavior begins to look more similar to that of adults. They may express their depressed feelings as well as suicidal thoughts. They may have difficulty feeling pleasure and show signs of low self-esteem, apathy, withdrawal, and low motivation. Poor school performance is common as are physical complaints, oppositional behavior, social problems, and delinquency

Pre-adolescents and adolescents ages 12-18 years are more likely to “act-out” their depression. They may show volatile moods, rage, various forms of delinquency, substance abuse, sexual promiscuity, suicidal thinking, self-abuse, and over-eating and sleeping. There may be guilt and feelings of worthlessness and the inability to concentrate and make decisions. School under achievement and suicidal thinking are also common.

It is estimated that 2-4% of our children under 17 yrs. Suffer from a major depression and the percent for teens is about 7%. There is no apparent difference in depression rates between boys and girls until about 11 years of age. After this time girls are twice as likely to be depressed as boys.

Causes of Depression

There are many causes of childhood depression. Genetics and changes in brain chemistry appear to play a role as does child abuse, abandonment, divorce, and loss of a loved ones to death or divorce. Other factors that are traumatic or negative life events can also be involved, such as rejection by significant others, imitation of significant depression in others, learning to be helpless, and the loss of rewarding people, things, and conditions. The factors that cause child and adolescent depression are similar to those that cause adult depression. Depression may go undetected by others until they intensify and are identified later in adult years. Frequently, adults will admit that they do not remember a time when they were not depressed. This is regrettable, because depression can severely limit ones success throughout life.

Depression can be improved or cured

A 16-year-old adolescent was brought to a therapist because he was flunking his tenth grade classes and was “into” Goth dress, literature, music and friends. He had ceased communicating with most people, stayed in his room at home, and was found to be using marijuana and cigarets. The teen would not communicate with the therapist. As a result of the various dangers involved in this case, the parents were advised to enter their son in an adolescent treatment center for psychological assessment, intensive individual and group counseling and substance abuse treatment. A psychiatrist prescribed antidepressant medication and after about two weeks he was discharged to his parents care and returned to his psychologist for further out-patient family and individual counseling. The teen’s thoughts, emotions, and behaviors gradually improved greatly in all ways.

It is important to review the known causes of Depression because in doing so we are in a better position to prevent, catch early and effectively treat depression in ourselves and our loved ones. If depression appears to be a problem in your children, schedule a visit with your family physician and also consider a a careful evaluation by a psychologist. Depression is a very treatable problem and it can often be cured.

An once of prevention is worth a pound of cure!

Oppositional-Defiant Disorder in Children

Oppositional-Defiant Disorder in Children

Symptoms

An all too common problem in our children is Oppositional-Defiant Disorder: This diagnosis is not given to children over 18 years of age, or to those who qualify for a more problematic diagnosis of Conduct Disorder (discussed preveiously).

Oppositional-defiant disordered children are disobedient, hostile, defiant, and negative toward authority figures. They fight compliance with instructions or requests and they are stubborn and will not compromise with adults or friends. They often test limits and do things to purposefully annoy others. These children show frequent hostility to authority figures and peers by arguing with and, in other ways, deliberately annoying them. They also purposefully break the rules that they are reasonably expected to follow. Oppositional-defiant children are often angry, resentful, spiteful and vindictive. Generally, their aggression remains at the verbal level and any physical aggression, if it occurs, remains mild to moderate in nature.

The oppositional and defiant behaviors displayed by these children are often focused intensively upon those who they are closest to (at home with parents and siblings), but they can also be directed at anyone who sets rules or limits upon their behavior. Psychologists and other therapists may not see a child’s oppositional-defiant behavior in their office (even with the parents present) but it will be abundantly present at home and sometimes elsewhere too. A child’s oppositional-defiant behavior may or may not be in evidence at school.

Rates of Oppositional-Defiant Disorder have been estimated to be from 2 to 16%, depending upon the populations sampled and the measures used.

Over the past 40 years, I have been called into schools to consult with teachers and principals to help with student’s behavior problems. I am convinced that oppositional-defiant rates have increased substantially. Rates of occurrence are higher for males before puberty, but are more equal between males and females after puberty is reached. Even so, males tend to be more confrontational than females.

These children may also show other psychological disorders such as ADHD, depression, anxiety, or learning and communication disorders.

Case Study

One adolescent male was born and raised in a family where the father was exceedingly demanding upon him. His mother was permissive and protective towards the boy and there was almost constant conflict between she and her resentful and compulsively demanding husband over the boys disciplinary issues. The boy was very bright and got good grades at school, but the father insisted upon all A’s stating that he was not living up to his potential. The boy’s behavior at school was exemplary and he was in various clubs and athletics. However, at home, he was manipulative and demanding of money, car privileges, and excessive freedom. His father almost always said “no” to these demands and his mother almost always countermanded the father’s judgement. The adolescent’s tactics involved angry, insulting and disrespectful behavior, and noncompliance with the requests of both of his parents. But, he was most likely to focus his blustery and unrelenting tantrum-like demands upon his mother. This was especially likely when his father was not at home. The mother frequently gave-in to her son’s demands. As you might guess, this rewarded the boy’s behavior and set the occasion for the next round of arguments between the mother and father. This adolescent’s oppositional-defiant characteristics appeared to be born of his parents polarized disunity, his resulting ability to further split and alienate them from each other, the ensuing conflict between the parents, and the family chaos that resulted. The adolescent was therefore in a better position to divide and conquer his parents authority in the future.

Suspected Causes

Oppositional-Defiant Disorder is more prevalent in families that have had many different care-givers and where inconsistent, harsh, abusive or neglectful child rearing methods have been used. It is also more likely to be found in homes where at least one parent has had a mood disorder (depression/bipolar), or other similar, perhaps more intense, disruptive disorders

Oppositional Defiant Disorder is more prevalent in males and children who are temperamental and show low self-esteem and low frustration tolerance. This disorder thrives on disorganization and is more common in homes where there have been many care-takers. Im my experience divorce or multiple mates and pregnancies out-of-wedlock frequently set the stage for this kind of chaos. Also, harsh or abusive treatment, irresponsible and neglectful parents, or significant mental illness, is frequently involved in the lives of children who show Oppositional-Defiant Disorder. Sometimes all that is necessary for the development of this problem is a clash between two parenting styles, one very demanding and the other very permissive.

Prevention or early correction

In many cases, parents can prevent these problems, they will recognize the development of this problem early and seek the assistance of an experienced behavior therapist with very good counseling and behavior modification skills. Almost always, with early intervention and treatment, the problem of oppositional defiant behavior in young children can be improved significantly.

Please pass this on to others who may need to know.

Conduct Disorder In Our Children and Youth

Children diagnosed with conduct disorder show a repetitive and persistent tendency to disrespect and violate the rights of others and to break normal societal rules and also laws. Conduct Disorder may be identified in children before 10 years and up to 18 years of age. It can be diagnosed in individuals older than 18 years, but only if they do not meet the criteria for Antisocial Personality Disorder which I will discuss in a later blog. Briefly, Antisocial Personality Disorder is a life-long disorder that is more severe than Conduct Disorder. The early appearance of Conduct Disorder in a child makes it more likely that the problem will continue into Antisocial Personality disorder in adulthood.

Conduct Disorder may be classified as mild, moderate or severe in nature. Frequently, children with mild cases of this disorder can be helped with therapeutic interventions and the problem may improve with maturity. Severe cases are more likely to continue into adulthood and form a long-term pattern of deeply ingrained antisocial behavior patterns that are highly resistant to change. The majority of our prison populations would be diagnosed as Antisocial Personality Disordered.

The list of actions shown by the children diagnosed with Conduct Disorder can be alarming. A partial list of such behaviors is as follows:

Recklessness and risk-taking
Curfew violations
Truancy from school
Running away from home overnight or longer
Lying, deceiving or “conning” others
Early sexual activity
Tobacco, drug and alcohol use
Bullying, threatening, intimidating and fighting
Using weapons (stones, clubs, knives, guns)
Breaking and entering homes, cars, or other buildings
Cruelty of people and/or animals
Property destruction (vandalism)
Robbery, extortion, mugging, purse snatching (while confronting the victim)
Assault and, rarely, murder

Conduct Disorder has increased in prevalence over several decades and rates are around 6% to 16% for males and 2% to 9% for females.

Suspected Causes

Many very bad childhood experiences appear to be tied to the development of Conduct Disorder. Parents who are drug involved, or have mental disorders of their own are more likely to have conduct disordered children. Research also suggests that the tendency to develop Conduct Disorder behavior patterns is genetically inheritable. Children so diagnosed frequently have experienced traumatic events, poverty, family disorganization, abuse, neglect, and abandonment. They have frequently lived in poverty and grown up around violent peers and adults. Children with a biological or adoptive parent with Anti-social Personality Disorder or a sibling with Conduct Disorder, are themselves at greater risk for developing a conduct disorder.

A Case Study

One 15 year old’s father was in prison for killing someone. The boy had visited his father in prison on numerous occasions and sometimes got phone calls from him. Despite his father’s pleadings to him to do good in school, follow the rules and stay out of trouble, the boy was failing in school, frequently suspended, and had been in a juvenile detention center for threatening and attacking other students. The boy’s mother had lived with several other men in the course of his short life-time and he had experienced drugs, violence, and the physical abuse of his mother and himself repeatedly. After frequently running away from home and being involved with older men and drug abuse, he was placed in a long-term adolescent treatment facility. The boys Conduct Disorder was severe in nature, with an early onset, and it was likely that his behavior patterns would continue into adulthood and then be diagnosed as Antisocial Personality Disorder.

We must find ways to save our infants and children from these incredibly damaging influences. The majority of these human tragedies can be prevented before their contagious effects spread throughout our population. Our current late remediation strategies are failing miserably and are doomed to fail by the very nature of this intractable psychological disability.

America must create bold preventive and very early interventions to avoid the continued escalation of the social havoc that we now experience due to our increasing rates of Conduct Disorders.

If you see the symptoms listed above in your own children, or a Friend or family member complains about them in their children, the best advice is to get professional help as soon as this behavior pattern begins to take shape. I recommend a conference with your family MD and if there are no health issues, an appointment with a psychologist with both counseling and behavior modification skills.

"An Once of Prevention Is Worth A Pound Of Cure"

"An Ounce Of Prevention Is Worth A Pound Of Cure"

Dear Parents,

Sailors do it the old and traditional way. They are more interested in enjoying the voyage than simply looking forward to reaching their destination. This is a great lesson for our parenting years, and life in general!

Though I did my best to enjoy my parenting years, I often find myself wishing that I would have taken even more time to appreciate and enjoy my my time with our young children and adolescents.

There is yet another lesson for parents, straight from our sailing heritage. Sailing a sailboat can be a wonderful, relaxing, and fulfilling experience. It can also have its times of danger, fear, and anxiety. Sailors are taught to "reef", or reduce their sails, at the first signs of a big blow, or a storm. It is unnecessarily hazardous to wait until the ship is in a big storm to go on deck and attempt to get the sails under control.

In all things, prevention is the best policy.

A very long time ago, I learned that helping parents who's children were showing psychological/behavioral problems normally worked best when when the children were young and/or, the problems were early in their development.

After over 30 years of psychological practice, I can tell you that this observation still holds true and I now consider it to be a very important Principle of Psychological treatment.

There is no reason for high anxiety. Developing children are constantly changing, as is their behavior patterns. Enjoy the process!

However, if emotional or behavioral problems appear to be emerging, monitor the situation carefully. If the difficulty continues for several weeks, or appears to be getting worse be sure to check with your pediatrician or family doctor. It is very important to rule-out any medical problems and get a professional opinion regarding the seriousness of your child's developmental problem.

If your concerns are validated, or if you still have uneasiness about your child's emotions or behaviors, do not be hesitant to consult a Licensed Child Psychologist in your State. It will be especially beneficial if this professional is skilled in Behavior Modification methods with children. The knowledge you will gain can give you confidence and help you to prevent the development of more serious problems in your child.

Remember to "reef "early! "An ounce of prevention is worth a pound of cure".
