There are many probable causes that have been thought to be associated with split personality disorder. These include a trauma that is being withheld from the subconscious and therefore the individual creates a personality as a coping method to be able to forget about the trauma. Others believe that certain disorders within the brain can cause the disorder to form and the individual to create other personalities within the mind.

Signs of a split personality disorder may include a complete loss of identity and may even include the patient being unable to remember activities and events that have occurred while the person was under the control of the alter personality. Some experts believe that the individual may exhibit uncharacteristic changes in behavior, even in the base or the original personality and may recluse themselves from family members and friends – shutting out the support system. Other signs may include a gap in memories of certain events or the onset of depression and mood disorders.

In order to understand the relationship between alcohol and depression it is important to understand depression itself. Depression is characterized by sadness and despair that can come in bouts and last upwards of months and even years. The origin of depression begins within the brain and stems from an imbalance of certain hormones and chemicals which assist in stabilizing the mood.

When alcohol is ingested, it acts as a depressant – rather than other substances which can act as a stimulant. Therefore, if the individual is depressed before consuming the alcohol, they may become additionally depressed or saddened because of the effects of the alcohol that has been ingested.

To fight the depression that comes with alcohol it is important to reduce the alcohol that is ingested.  This can be done through the use of cutting the habit completely or taking part in a program that allows the individual to take support from friends and family members to avoid drinking alcohol. Something as simple as taking time to enjoy activities that are not dedicated solely to drinking and making a change within the lifestyle can be an effective way to reduce the dependence on alcohol.
