Lacunar Amnesia

Lacunar amnesia is the loss of memory about a specific event. This specific form of amnesia is caused by brain damage in the limbic system which is responsible for our memories and emotions. When the damage occurs it leaves a lacuna, or a gap, in the record of memory within the cortex region of the brain. There is a general belief that certain emotions from the lost memory may be triggered without the recollection of the event.

Characteristics

Daniel Goleman, in his book Vital Lies, Simple Truths, defines a lacuna as:

“…the sort of mental apparatus that diversionary schemas represent. A lacuna is, then, the attentional mechanism that creates a defensive gap in awareness. Lacunas, in short, create blind spots.”[1]

Lacunar amnesia has also been known to be attributed to alcoholism, drug treatment, and withdrawal in some cases. After using these substances a person may experience a loss of memory of a specific event temporarily or even permanently.[2]

Steven Johnson, (the author of Mind Wide Open: Your Brain and the Neuroscience of Everyday Life) also states that:

“Scientists believe memories are captured and stored by two separate parts of the brain, the hippocampus, the normal seat of memory, and the amygdala, one of the brain’s emotional centers. People who, due to hippocampus damage, are incapable of forming long-term memories can still form subconscious memories of traumatic events if their amygdala is intact. “This may be related to erasure or reconsolidation of memories. Attempts have been made to remember memories that have been consolidated and reconsolidate them under desired conditions.

According to Alex Chadwick speaking on NPR:

“Some scientists now believe that memories effectively get rewritten every time they’re activated. Studies on rats suggest that if you block a crucial chemical process during the execution of a learned behavior – pushing a lever to get food, for instance – the learned behavior disappears. The rat stops remembering. Theoretically, if you could block that chemical reaction in a human brain while triggering a specific memory, you could make a targeted erasure. Think of a dreadful fight with your girlfriend while blocking that chemical reaction, and zap! The memory’s gone.”

This idea of the reconsolidation of memories has also been used in cases of PTSD to lessen or alleviate some of the symptoms associated with the illness.   more

 

Brief Psychotic Disorder

Brief psychotic disorder (BPD) according to DSM-5 is the sudden onset of psychotic behavior that lasts less than 1 month followed by complete remission with possible future relapses. It is differentiated from schizophreniform disorder and schizophrenia by the duration of the psychosis. The diagnosis is often anticipatory or retrospective due to the diagnostic requirement of complete remission within 1 month.

Brief psychotic disorder is an acute but transient disorder with the onset of one or more of the following psychotic symptoms:

  • Delusions
  • Hallucinations
  • Disorganized speech
  • Grossly disorganized or catatonic behavior

At least one of these symptoms must be delusions, hallucinations, or disorganized speech. The symptoms in BPD last between one day to one month, with a complete return to premorbid level of functioning after the disease course in response to antipsychotic medications. The disturbance in behavior cannot be better accounted for by schizophrenia, schizoaffective disorder, mood disorder with psychotic features, or be a direct result of a drug, medication, or medical condition like thyrotoxicosis, sarcoidosis, or syphilis.

Etiology

Although unclear, the underlying etiology of brief psychotic disorder can be a stressful event or trauma. There may be a genetic, neurological, or environmental component to BPD as well. The specific trigger of BPD, if present, must be specified as follows:

  • Brief psychotic disorder with marked stressor(s) is also referred to as brief reactive psychosis. It is the onset of psychotic symptoms that occur in response to a traumatic event that would be stressful for anyone in similar circumstances in the same culture
  • Brief psychotic disorder without marked stressor(s) is the onset of psychotic symptoms that occur in the absence of a traumatic event that would be stressful for anyone in similar circumstances in the same culture
  • Brief psychotic disorder with postpartum onset is defined as the onset of psychotic symptoms that occur within four weeks postpartum   more

Bipolar Disorder with Psychotic Features

Some people who have been diagnosed with bipolar disorder will experience episodes of psychosis during mania or depression. These episodes cause hallucinations, delusions, disordered thinking, and a lack of awareness of reality. While in extreme situations hospitalization may be necessary, most bipolar patients with psychotic features can manage these episodes with ongoing, professional treatment.

Bipolar disorder can trigger psychotic symptoms, which may include hallucinations or delusions during mania, depression, or both.

Psychosis can be distressing, but it can also be managed, treated, and even prevented with the right medications and therapy with experienced mental health professionals.

What Is Bipolar Disorder?


Bipolar and related disorders are mood disorders characterized by episodes of mania and depression. Manic episodes cause a feeling of euphoria, unusually high energy and activity levels, and irritability. Depressive episodes cause sadness, hopelessness, fatigue, loss of interest in activities, and other symptoms of depression.

Depending on the type of the condition, a person with bipolar disorder may cycle through both of these moods or may experience depression with a less extreme type of mania called hypomania. A low-grade but long-term type of bipolar disorder is called cyclothymia. Bipolar I, the disorder that triggers both depression and mania, may also cause symptoms of psychosis.

Psychosis Is a Specifier for Bipolar Disorder


When a medical or mental health professional is diagnosing bipolar disorder they may use specifiers. These are added details that describe an individual’s experience and symptoms. Specifiers include atypical features, like significant weight gain or sleeping too much, and psychotic features. If someone is diagnosed with bipolar disorder with psychotic features it means he or she meets the diagnostic criteria for bipolar but also has symptoms of psychosis.

What Is Psychosis?


Psychosis is a state of mind and a set of symptoms characterized by losing contact with reality. It is not a condition in and of itself but rather a group of symptoms that can be triggered by certain mental illnesses, like bipolar disorder, and by medical conditions, brain injuries, substance misuse, and some medications. Someone with bipolar disorder may experience psychotic symptoms during a manic or a depressive episode. The specific symptoms and their character or content vary by individual.

Symptoms of Bipolar Psychosis


Exactly what one person will experience when having psychotic symptoms during an episode of mania or depression varies. However, in general psychotic symptoms can be grouped into a few categories:

  • Hallucinations. A hallucination is something that is sensed—heard, seen, felt, tasted, or smelled—that seems real but that is not real. Hallucinations may include seeing things that aren’t there or hearing non-existent voices.
  • Delusions. A delusion is a false belief that persists in spite of evidence. Delusions can be paranoid, grandiose, persecutory, jealous, or a mixture of types.
  • Confused thinking. Psychosis can cause disordered, racing, and irrational thoughts. To an observer this person may talk very fast, jump from one topic to another, and not make a lot of sense.
  • Poor self-awareness. In the middle of a psychotic episode a person will not be aware that his or her beliefs or hallucinations are false. This can trigger fear and significant distress.

Psychosis in bipolar disorder tends to match a person’s current mood. So, for instance, during mania a person may have grandiose delusions, believing he or she is more talented and capable of doing something, or even famous and rich. During a depressive mood those delusions will take a downturn, and may include things like the paranoid belief that someone is out to get them.   more

Dissociative identity disorder (DID) [formally known as multiple personality disorder]

DID Fact Sheet

What Is Dissociative Identity Disorder (DID)?

Dissociative identity disorder (DID), previously referred to as multiple personality disorder, is a dissociative disorder involving a disturbance of identity in which two or more separate and distinct personality states (or identities) control an individual’s behavior at different times. When under the control of one identity, a person is usually unable to remember some of the events that occurred while other personalities were in control. The different identities, referred to as alters, may exhibit differences in speech, mannerisms, attitudes, thoughts and gender orientation. The alters may even present physical differences, such as allergies, right-or-left handedness or the need for eyeglass prescriptions. These differences between alters are often quite striking.

A person living with DID may have as few as two alters or as many as 100. The average number is about 10. Often alters are stable over time, continuing to play specific roles in the person’s life for years. Some alters may harbor aggressive tendencies, directed toward individuals in the person’s environment or toward other alters within the person.

At the time a person living with DID first seeks professional help, he or she is usually not aware of their condition. A very common complaint in people affected by DID is episodes of amnesia, or time loss. These individuals may be unable to remember events in all or part of a proceeding time period. They may repeatedly encounter unfamiliar people who claim to know them, find themselves somewhere without knowing how they got there or find items that they don’t remember purchasing among their possessions.

What Are The Symptoms Of DID?

Often people living with DID are depressed or even suicidal and self-mutilation is common in this group. Approximately one-third of individuals affected complain of auditory or visual hallucinations.

While the causes are unknown, statistics show that DID occurs in 0.01 to 1 percent of the general population. DID is a serious mental illness that occurs across all ethnic groups and all income levels. It affects women nine times more than men.

In addition to experiencing separate identities, individuals living with DID may also experience many other symptoms. Some of these symptoms include:

Seasonal affective disorder (SAD)

Overview

Seasonal affective disorder (SAD) is a type of depression that’s related to changes in seasons — SAD begins and ends at about the same times every year. If you’re like most people with SAD, your symptoms start in the fall and continue into the winter months, sapping your energy and making you feel moody. These symptoms often resolve during the spring and summer months. Less often, SAD causes depression in the spring or early summer and resolves during the fall or winter months.

Treatment for SAD may include light therapy (phototherapy), psychotherapy and medications.

Don’t brush off that yearly feeling as simply a case of the “winter blues” or a seasonal funk that you have to tough out on your own. Take steps to keep your mood and motivation steady throughout the year.

 

Symptoms

In most cases, seasonal affective disorder symptoms appear during late fall or early winter and go away during the sunnier days of spring and summer. Less commonly, people with the opposite pattern have symptoms that begin in spring or summer. In either case, symptoms may start out mild and become more severe as the season progresses.

Signs and symptoms of SAD may include:

  • Feeling listless, sad or down most of the day, nearly every day
  • Losing interest in activities you once enjoyed
  • Having low energy and feeling sluggish
  • Having problems with sleeping too much
  • Experiencing carbohydrate cravings, overeating and weight gain
  • Having difficulty concentrating
  • Feeling hopeless, worthless or guilty
  • Having thoughts of not wanting to live

    Seasonal changes and bipolar disorder

    People who have bipolar disorder are at increased risk of seasonal affective disorder. In some people with bipolar disorder, episodes of mania may be linked to a specific season. For example, spring and summer can bring on symptoms of mania or a less intense form of mania (hypomania), anxiety, agitation and irritability. They may also experience depression during the fall and winter months.   more

Paraphrenia: Causes, Symptoms And Treatment

Paraphrenia is a type of mental disorder characterized by paranoid delusions. The affected individual experiences imaginary fears or anxieties that are often exaggerated, but do not undergo significant loss of intellectual capabilities, such as memory and daily routine habits.

Although paraphrenia presents symptoms similar to schizophrenia, it often occurs only in the elderly, above the age of 60 and is also quite a rare condition. Schizophrenia, on the other hand, is often reported in teenagers, young adults, as well as middle-aged people.

 

Paraphrenia is, in the majority of the cases, not a very severe ailment. Nevertheless, it is absolutely essential to seek immediate medical care, as soon as typical indications of paraphrenia are recognized in any older person, to ensure timely treatment and efficient management of brain-related irregularities.

Causes

The main factors contributing to the development of paraphrenia in aged persons include:

Severe Neurological Illnesses

When the brain undergoes significant physical modifications, due to a tumour, stroke, grave injury, nerve or blood vessel damage, other neurodegenerative conditions, it affects its normal functioning and response to external stimuli. These abnormal instances could give rise to paraphrenia.

Stressful Personal Situations

Older adults who do not engage in regular social contact, are extremely disconnected from normal events going on around them, have no family or friends and struggle to sustain themselves suffer from serious emotional trauma to the brain. These challenging circumstances, in some cases, lead to paraphrenia.   more
