Just link to some studies showing the 5 disorders listed are caused by trauma and/or brain damage. Shouldn't be hard to do if your claim is valid.

No moron. It's in the name. Trauma and stress.
Attention-deficit/hyperactivity disorder (ADHD) is a prevalent neurobehavioral disorder affecting 5% to 10% of children. Although considered to be a highly familial disorder, ADHD heritability estimates of 60% to 80% highlight the considerable role that environmental factors may still play in disorder susceptibility. Proposed ADHD environmental risk factors include prenatal substance exposures, heavy metal and chemical exposures, nutritional factors, and lifestyle/psychosocial factors.

The role of environmental factors in the development of autism is a crucial area of study. We know that genetics strongly influence the risk for developing autism spectrum disorder (ASD). However, genetics alone do not account for all instances of autism. For good reason, the increasing prevalence of autism has generated great interest in the potential involvement of toxins in our environment. For example, prenatal exposure to the chemicals thalidomide and valproic acid has been linked to increased risk of autism.

While people are genetically predisposed to be at risk of the disorder, not all of these people develop bipolar disorder. This suggests that environmental factors and psychological factors can trigger manic or depressive episodes, although not everyone with the disorder will experience a triggering event.

Comorbidity between MD [major depression] and alcoholism in women is substantial and appears to result largely from genetic factors that influence the risk to both disorders, but common environmental risk factors also contribute. However, genetic factors exist that influence the liability to MD without influencing the risk for alcoholism and vice versa. Narrowing the diagnostic criteria for MD or alcoholism increases comorbidity, but for different reasons narrow diagnostic criteria for MD increase the environmental sources of comorbidity while narrow diagnostic criteria for alcoholism increase the genetic sources of comorbidity.

Genetic factors are clearly important in the etiology of schizophrenia, but the environment in which an individual's genes find expression is also crucial to the development of the illness. In this review of environmental risk factors for schizophrenia, we consider risks operating prenatally and perinatally, during childhood, and then later in life prior to illness onset. Some of these risk factors have been well documented, for example, early hazards causing fetal growth retardation or hypoxia, and hazards nearer the onset of illness like drug abuse and migration. Others are much less certain. The importance of interaction between genetic and environmental risk is, however, undoubtedly important and there is emerging evidence for this from a range of sources.

And even if they weren't, there is still a huge discrepancy between heredity and expression that genetics alone obviously cannot account for. And since a disorder cannot be said to "caused" until it is expressed, factors other than genetic are overwhelmingly the triggering causes.
A gene that is turned on or expressed is in fact genetic causation. There are many factors influencing this expression. Environmental isn't the only one. Other genes also cause genes to be expressed at certain times. Read up on genetics some time.
