Why does it happen? Well, researchers believe that depressive and manic episodes are the most common causes of memory loss in patients with bipolar disorder. During manic episodes, the individual may operate at high speeds, making it difficult for them to hard code new information into their memories.
People with bipolar disorder often report problems with memory and cognition. They have trouble with short- and long-term memory, think things through at subdued speeds, and have difficulty thinking outside that so-called box. These memory problems can pose considerable challenges for bipolar patients.
Impaired working memory is a core cognitive deficit in both bipolar disorder and schizophrenia. Its study might yield crucial insights into the underpinnings of both disorders on the cognitive and neurophysiological level.
Experts believe that bipolar disorder is associated with the smaller size of certain regions of the brain and with changes in the brain's chemicals. It can also cause changes in thinking and hallucinations. In some cases, it is unknown whether changes to the brain cause bipolar disorder or result from the condition.
Detection of mania, or at least of brief hypomania, is required for diagnosis of bipolar disorder. This diagnosis is often missed or not remembered as an illness. People close to the patient may recall episodes, however, and patients who do not remember episodes of affective disturbance may recall their consequences.
During a manic episode, people with bipolar disorder can have what's called a bipolar blackout. During a blackout, the individual is not aware of their surroundings or actions and has trouble remembering them afterward. This can make interacting with someone in a blackout very frustrating, but it doesn't have to be.
The exact cause of bipolar disorder is unknown. Experts believe there are a number of factors that work together to make a person more likely to develop it. These are thought to be a complex mix of physical, environmental and social factors.
A person with bipolar disorder will alternate between periods of mania (elevated mood) and periods of depression (feelings of intense sadness). In between these two extremes, a person will have periods of normal mood.
MRIs and CT scans can provide detailed images of the brain and its structures. But currently, doctors don't use them to diagnose bipolar disorder. Detecting bipolar disorder is typically done through a diagnostic interview with a mental health professional.
Bipolar disorder is frequently inherited, with genetic factors accounting for approximately 80% of the cause of the condition. Bipolar disorder is the most likely psychiatric disorder to be passed down from family. If one parent has bipolar disorder, there's a 10% chance that their child will develop the illness.
Bipolar disorder can also make it difficult to concentrate. When you're in the midst of a manic phase, you might find your mind racing and have a hard time controlling your thoughts. You may even talk faster than usual.
Studies show that bipolar disorder mood swings or episodes may affect working memory processes, mainly updating memory and serial recall(8). Researchers also noted that individuals with the condition may have poorer cognitive performance even after episode symptoms have subsided(9).
Bipolar may worsen with age or over time if this condition is left untreated. As time goes on, a person may experience episodes that are more severe and more frequent than when symptoms first appeared.
The risk of developing dementia is much higher among people who've had bipolar disorder, according to several studies. A 2020 analysis determined that people with bipolar disorder are about three times more likely to develop dementia, while another expansive analysis also found a significantly increased risk.
There are no specific blood tests or brain scans to diagnose bipolar disorder. Even so, a doctor may perform a physical exam and order lab tests, including a thyroid function test and urine analyses. These tests can help determine if other conditions or factors could be causing your symptoms.
Brain Changes
Research shows bipolar disorder may damage the brain over time. Experts think it's because you slowly lose amino acids. They help build the proteins that make up the insulation around your neurons.
Bipolar disorder (BD) is a mental health condition associated with shifts in mood and energy levels and other symptoms. A person with BD may experience episodes of mania or elevated mood, depressive episodes, or “mixed” episodes with manic and depressive symptoms.
During bipolar mood swings, it is difficult to carry out day-to-day tasks, work, go to school, and maintain relationships. When a person has a manic episode, they feel overly excited, productive, and even invincible. These drastic behavior changes usually cause concern among friends and family.
“Many people think that a person with bipolar disorder doesn't have any control over themselves or that they're unable to take care of themselves or function in society. This simply is not true,” says Ikaika King, who was diagnosed with bipolar II when he was 17.
People with bipolar disorder have fewer social interactions and smaller social networks than healthy comparison subjects (5, 6) and are less likely to achieve social milestones such as marriage or equivalent relationships than the population as a whole (7).
Defects in mitochondrial DNA sequences may contribute to a predisposition to such complex diseases as diabetes and bipolar disorder. Therefore, if all bipolar disorder patients have mitochondrial predisposition genes, then the transition of bipolar disorder from the mother's side would be higher.
Bipolar disorder often runs in families, and research suggests this is mostly explained by heredity—people with certain genes are more likely to develop bipolar disorder than others. Many genes are involved, and no one gene can cause the disorder. But genes are not the only factor.
Childhood trauma
Some experts believe that experiencing a lot of emotional distress as a child can cause bipolar disorder to develop. This could be because childhood trauma and distress can have a big effect on your ability to manage your emotions. This can include experiences like: Neglect.
What's more, many people with bipolar disorder report memory loss and or difficulty remembering things. These individuals may have trouble with short and long-term memory, struggle to think things through at a quick speed, and have difficulty thinking outside of the so-called box.
Delusions can be a symptom of both manic and depressive episodes in people with bipolar disorder. These false beliefs can be very distressing to anyone who experiences them. If you're concerned about delusions in yourself or a loved one, seek help from your primary care provider, a psychologist, or a psychiatrist.
