Forgetfulness and Memory Loss at Work

Memory loss results from disruption at any of these processes

Forgetfulness and Memory Loss

Forgetfulness or failure to remember information, is a common complaint. All of us have at some time or the other forgotten to make that important call, to pick up some items from the store, an anniversary or birthday, or a colleague’s name. Students forget what they have “learnt” during exams. We often can’t remember where we have left our car keys, our wallet or that important document. Is it normal? And more importantly; when do we need to seek help?

Forgetfulness or memory loss and difficulty concentrating are common symptoms of mental health disorders. This is specially so in depression, anxiety disorders, ADHD (Attention Deficit Hyperactivity Disorder), and dementias as shown in the examples below.

A young working professional seeks help for increased forgetfulness and poor ability to focus at work. Further probing reveals decreased interest in doing things at work and home. She is also irritable, depressed and her sleep is disturbed. These symptoms of low mood can exist in the background of memory loss and problems with focus.

A student during exams has high anxiety causing memory loss. She cannot recall the answer to a certain question. She gets nervous. This causes her to make mistakes in the next question. She tends to panic; fail to recall what she studied. This vicious cycle is common in anxiety disorders and can manifest as problems with concentration, memory and forgetfulness.

An older person does not just forget the name of his neighbour (something that may happen to any of us); but also who she is. He has problems using money, and with shopping. Difficulties at work manifest towards the end of the career. Dementias affect the aged; cause memory loss and affect the context of the memory.

A young professional has problems organising and completing projects at work. There may be a history of attention and academic problems in school. Working memory gaps are common in this group. ADHD is a common cause of this problem in adults.

Memory Processing in the Brain

To understand further, it helps to know in brief how memory works. It is a 3 stage process

Encoding: The stage when sounds, images and other sensations are given meaning is called encoding. Sensations are coded electrically for access by other brain areas. (We hear a catchy song from a new movie).
Storage: The process of association or tagging the input with other bits of data to make it persist. The song thus gets stored in our long term memory. Initially, the song remains for a very short while. At this point it is in our working or short term memory. It is encoded. However, we forget the song as the next scene unfolds on screen. The song is repeated at the end of the movie; someone hums the song as we leave the hall. The visuals of the song, and the feelings evoked, the fact that it was a famous actor, then reinforce the memory and makes it persist.
Retrieval: When we need to use this stored data, the brain fishes it out from its long term memory. The more the associations or tags we formed earlier, the more easily the brain can access the information.

Problems in memory can therefore occur at any of these stages. Many of these occur at the stage of encoding because we are simply not paying attention; and many other distractions are vying for our focus at the same time. (e.g checking our FB messages while studying). The brain does not multi-task, it can only do one thing at a time.

Repetition, rehearsal and organisation help in fixing and storage of long term memory. The more widespread and elaborate the connections, and the more data available about an input, the more the connections formed by the brain, and the easier it is for the brain to retrieve the information when required. Many cases of forgetting are due to retrieval failures. The information is there in long term memory but we are unable to access it. This is why we can recall certain things at a later date.

Depression affects memory in many ways. Being unable to concentrate is a symptom of depression. Repeated depressive thoughts also block the learning process through distraction. This affects the stage of encoding. Disturbed sleep which is a common symptom in depression hampers fixing into long term memory.
Forgetfulness is common in ADHD of adults. ADHD lowers the power to focus. The person is easily distracted. The attention span is reduced. This impairs short term or working memory. ADHD persists in up to 40% of aduts.
Anxiety gives rise to pointless thoughts (“my father will be so angry if I don't crack this exam”) which frustrates attempts to retrieve the matter learned. The anxiety provoking thoughts distract from the text which is being studied and impedes the encoding process.
In dementia there is destruction and loss of brain cells. Dementia blocks all stages of the memory and learning process. The process is not reversible.

Forgetfulness and Memory Loss – when to seek help?

When it affects our work, or the quality of our work
When the failure to learn and recall affects our daily activities and functioning
When there are also problems including sleep, appetite, inter-personal or behaviour changes.
When it is strange - leaving keys in the fridge
When it can harm - often leaving cooking burner on, leaving doors unlocked at night

In normal forgetfulness, the person may recall the memory when some cues are given. The memories were encoded, they just needed some reminder to access them. In clinical disorders resulting in memory loss the memories were never laid down in the first place, or the storage structures in the brain are destroyed. Access to these memories may not be possible.

OCD – Obsessive Compulsive Disorder

What is OCD?

OCD – Obsessive compulsive disorder – is a severe type of anxiety disorder involving obsessions and compulsions that affects the day-to-day functioning of a person.

What are obsessions?

Obsessions are thoughts, images, or impulses that occur over and over again; cause severe anxiety; feel outside the person’s control and affect the day to day functioning of a person.

What obsessions are not

Most of us know what it is like to be preoccupied with a thought, idea or even a person sometimes. These are not obsessions. They often give pleasure, usually pass off soon and do not affect our daily routine or work. Certain types of personality are also linked to a fastidious concern for details and “correctness”. However, this is not associated with anxiety and hence not an obsession.

What are compulsions?

Compulsions are repetitive behaviours aimed at decreasing the anxiety associated with the obsessions.

What compulsions are not

Not all repetitive behaviours are compulsions. Bedtime rituals, religious practices, learning new skills involve repeating an activity. Behaviours also depend on the condition and situations of a person’s life. Arranging wares back on shelves are a normal part of a shop assistant’s work and are not compulsions.

Types of obsessions and compulsions in OCD

Contamination: Contamination is among the commonest of obsessions. There is a fear of dirt, germs, waste, toxins or body secretions. A person is afraid of getting an illness or spreading it. Sometimes he/she may just have feeling of “not being clean”. Touching an “unclean” object or even being near it may cause extreme anxiety. This is only eased by repeated washing and cleaning. Often the washing has to be done in a particular way or be repeated many times before he/ she feels clean again. The person also goes through great trouble to avoid or prevent contact with the contaminants. In time, they may become house-bound and force family members to also follow these cleaning rituals.
Pathological doubt: A person worries all the time that he will cause some harm to himself, his family or others due to his own carelessness. ‘Did I lock the door?’; ‘Did I switch off the lights?’; ‘Is the gas turned off?’ This constant questioning, doubt and responsibility leads to a compulsion to check and recheck. He may need to check the gas switch and the locks so many times that he gets late for work or is unable to sleep at night. Though he knows that the task is complete, his compulsive, repetitive behaviour continues.
Perfectionism and need for symmetry: A person has a need to do or arrange things “perfectly”. Items on his desk have to be placed in a certain way; or his shoes may need to be stacked in an exact order. He may need to perform certain actions or behaviours a certain number of times or in a precise order to have a sense of ‘completeness’. A child with OCD may worry that his homework is ‘not quite right’ and spend hours checking, erasing and re-doing his work because his T’s are not crossed properly. A person at work may feel that the day will go badly for him if he does not take a certain number of steps (say in multiples of seven) to his desk.
Concern about illness and disease: A person may have an irrational fear of developing a serious or incurable illness-usually HIV, heart disease or cancer. He may consult doctors and visit hospitals repeatedly. Despite normal medical reports and reassurance he will get investigations done again and again.
Distressing sexual thoughts and images: 'Sinful' religious images are other common obsessions. This specially occurs near religious places or during religious rites and rituals. He may feel intense guilt and avoid such places or services in the future.

OCD Treatment

Treatment of OCD consists of cognitive behaviour therapy (CBT) and medication. OCD treatment is best done as early as possible, as chronic OCD can affect daily life, work and relationships. CBT is essential for all patients with OCD. CBT tackles the obsessive thoughts [Cognitions-C]; the compulsive behaviours [B] in a methodical way [Therapy-T]. CBT by itself can reduce symptoms and delay or prevent relapses.

OCD medication may be required when symptoms are moderate or severe. Medication for obsessive compulsive disorder is usually combined with CBT. The outcome of therapy also depends on family support; and the patient’s own insight, motivation and readiness for change.

ADHD and Me

Hi. I’m Jai. I’m 8 years old. This is my story. My doctor says I have an illness. I don’t feel sick. But I do know that grown-ups around me are annoyed with me most of the time. I’m constantly being told, “sit still’’, “stop dreaming”, “pay attention”. I can’t seem to be able to do just that.

In class, I seem to lose track of what the teacher says. I try to listen, I really do. I start doing what she says, then I notice the insect fluttering on the window pane, I see the boy in the row ahead tapping his fingers on the desk, the office boy walking down the corridor and the sound of laughter from the next classroom. I don’t realise I have left my seat till teacher tells me “Jai, return to your seat”.

My parents are frequently called to school to meet my class teacher. They are unhappy with my marks. They think I’m careless and lazy because I take all evening to do my homework. I tell my mother that I try hard. I feel sad and frustrated that she doesn’t understand or believe me. Some of the other children make fun of me specially when I can’t answer in class. Mostly, I haven’t heard the question. They don’t like to play with me as I get excited and can’t wait for my turn.

Things changed about 6 months back. My parents took me to a special doctor. The doctor seemed to understand that I was not being naughty or disobedient. He talked to me, looked at my exercise books and listened to my parents. He told my parents that I had an illness, ADHD. I needed medicines for treatment of ADHD to improve my focus and concentration. I also need structure and routine in my life. It was such a relief to know it was not my fault.

A lady at the doctor’s clinic gave me some puzzles and games to do. I liked her; she spoke slowly and clearly. She explained things one at a time and did not mind repeating herself when I did not get her the first time. She helped us draw up a time-table - we had such fun doing that because she made time for everything I want to do. Now I have a study time, a play time, TV time, all clearly written in the big chart I helped to make. It reminds me of what I have to do and gives me enough time to prepare for it. Mother says I sit quietly for longer periods. Teacher says I pay more attention and don’t disturb other kids in class. She is more patient with me too.

Understanding ADHD and Helping Me

Doctor says there are many children like me. Here’s what you can do to help me and others like me.

Help me focus. Make sure I’ve heard you and understood what you want me to do.
I sometimes don’t realise I’ve left my seat. Please remind me to stop and think.
I need structure and routine in my life.
I need to know what comes next.
Please give me time to adjust to any changes in my schedule.
Please let me learn at my own pace, I get confused and make mistakes when you ask me to hurry up.
Please give me instructions one step at a time. Make me repeat them.
Please give me short work periods and small goals to start with.
Please give me immediate feedback; did I do things the right way?
Do give me praise even if I succeed only partially. Please don’t wait till I’m perfect.
Don’t always find fault with me. Please praise me and reward me when I do something well.

Thank you for being patient with me.

Dealing with Grief

Dealing with grief is a process of acceptance

Grief is the response to losing someone to death. All of us understand that death and loss of a loved one is a part of life. However, the reality of death often leads to feelings of shock, sadness and confusion. Acute grief occurs in the immediate aftermath of the loss. It is intensely painful characterised by sadness, crying, constant thoughts of the deceased, disturbed sleep, appetite and disinterest in one’s own self and others. In a majority of cases, this is followed by integrated or abiding grief in which memories of the loved one mingle with sadness and longing but it does not persistently occupy the mind or disrupt normal day-to day activities.

“Well, everyone can master a grief but he that has it.”

William Shakespeare. Much Ado About Nothing. III.ii.25

Loss through death affects each of us differently. How one feels depends on the nature and circumstances of the loss, one’s beliefs and religion, age, relationships and one’s own physical and mental health. A sudden or violent death, death of a child or loss of a long-time spouse are always more difficult to accept. If the relationship with the departed person was difficult, the grief is more complicated and may take more time to work through.

Stages of grief

5 stages of the grieving process has been described. The stages do not necessarily come in order, nor are all the stages experienced by every person. One may return or go through one or the other stage several times before acceptance of the loss.Grief is a process and not just a state. During the process of grieving and bereavement a person may experience many emotions during the course of bereavement- helplessness, anger, sadness, denial, despair and yearning are common.

Denial: The first stage is the stage of denial ('It's not true’; ‘There must be some mistake.’) This is a normal defence mechanism which helps to cushion the immediate shock.
Anger: Once the reality sinks in, the pain is often redirected and expressed as anger. ‘Why me?’; ‘Its not fair’; ‘How can this happen to me’; are the common reactions in this phase. Anger may be directed towards objects, strangers, the doctors or family members, God; or even towards the deceased person- ‘How could you leave me alone?’
Bargaining: A promise of good behaviour or an attempt to strike a bargain (‘I will always listen to you’, ‘I will never worry you again,)’ is often the reaction at this stage.
Depression: Sadness and regret are mingled and one may often say ‘There is no point in life; - I may as well die too’.
Acceptance: At this stage emotions are stable and calm.

Strategies for dealing with grief

Though each one copes differently, the following strategies may help you cope with your feelings and come to terms with your loss.

Talking about your loss: It may be difficult for you initially- but in time it helps to talk about your loss and your feelings with a trusted family member or friend or a counsellor.
Accepting your feelings : The anger, guilt, helplessness you may feel are normal and part of the grieving process. There is no guilt or shame in accepting them; and it paves the way for healing.
Taking care of yourself : Establishing a routine with regular meals, exercise and adequate rest is important for your physical and mental health.
Reaching out to others: Working with people less fortunate, or carrying on the legacy of the deceased (teaching, helping in the community) helps to give meaning to life.

When to seek professional help

Though different people take different times, intense and persistent grief continuing over a period of six months may require professional help.
Loss due to suicide is among the most difficult to bear. In such cases, counselling during the first weeks is both advisable and beneficial.
Inability to cope with or resume daily life or work activities, intense sorrow or pain which does not subside with time, inability to maintain or build relationships are indications to consult a mental health specialist.

Recovery from grief is a highly individual process. Each individual works through grief on their own with time, using their own personal ways of coping. Acceptance, rationalisation, humour, distraction, prayer, avoidance of reminders are some of the many ways in which people cope. Social support and healthy habits contribute to recovery which may take a few months or even a year.

Mental Illness Myths and the Media

Media portrayals of mental illness propagate prevailing myths and increase associated stigma.

Media and Stigma

Mass media – TV, cinema and newspaper – are the primary source of mental health information for the general public. The mentally ill are usually shown in poor light; and images of unkempt, violent and dangerous men predominate. This greatly affects the public’s view of the mentally ill, causing them to fear, avoid or discriminate against people with mental illness. This is even true for TV programs and stories for children. From an early age mental illness is seen as less desirable than other illnesses.

Negative images such as these affect those with mental illness, damaging their confidence and self-esteem. It makes them more isolated and withdrawn and they are more likely to stay away from therapy. In one study, as many as 50% of patients reported that a negative media portrayal had a negative impact on their illness, with 34% saying that it directly led to an increase in depression and anxiety.

Government policies are also affected by prejudiced media portrayals of mental illness. Since people with mental illness are seen as anti-social, prone to violence and a potential danger to society, government policies tend to restrict and isolate instead of being more broad-based.

5 Media Myths on Mental Illness

Myth 1 – People with mental illness are violent and unstable: Almost two-thirds of all stories about the mentally ill in both the news and entertainment media focus on violence. While it can happen, most violent crimes are in fact committed by people without mental illness. But a crime committed by a person with mental illness is blown out of proportion by the media instead of being seen as something rare and out of the ordinary. Studies in fact indicate that the mentally ill are more likely to be victims of violence rather than the offenders.
Myth 2 – They do not get better and treatment is ineffective: The truth is that even severe psychiatric disorders can be treated effectively and people can lead normal lives at work, at home and in the community. While treatment of psychiatric disorders has evolved, the media continues to show outdated practices. This highly inaccurate portrayal often prevents both the mentally ill and their families from seeking treatment.
Myth 3 – Mental health professionals are evil, mentally unstable, or unethical: The diagnosis and treatment of mental health disorders requires patience, skill and comprehensive evaluation. Mental health care professionals spend years in acquiring the qualifications and training required. Yet media portrayals undermine the integrity of these professionals. This further discourages people who are already hesitant to seek treatment.
Myth 4 – Teenagers with mental illness are just going through a phase: This encourages parents of teenagers to ignore symptoms as something that teenagers will outgrow. Movie portrayals of the teenager as a ‘rebellious free spirit’ further glamorises it in the eyes of the teen. The truth is that the onset of many serious psychiatric illnesses is in adolescence or early adulthood and early treatment offers the best outcomes.
Myth 5 – There is a genius behind every mental illness: While some people with mental illness are undoubtedly gifted, a vast majority of people with mental illness are ordinary individuals who want to get on with their lives and work productively. This caution is specially true for parents of children and adolescents; who view the role of the therapist as one who will unlock the hidden genius in their child. These unrealistic expectations put unnecessary pressure on children, often leading to a relapse; or a loss of faith in the treating clinician.

Sympathetic but exaggerated media portrayals may do more harm than good. Simple achievements need to be highlighted just as much. As an example, while the media annually highlights the success of children with physical disabilities in the board exams, yet no story deals with the successes of those with children struggling against schizophrenia and other mental illnesses. Sharing such stories will increase awareness among the public about how regular treatment and supportive therapy can help a child return to normal functioning.

The media’s defence is that the public is not interested in watching something dull and boring, and that they need to dramatize and exaggerate portrayals. However, authentic stories of mental illness have heartbreak, drama, humour and everything in between. Sensitive and accurate portrayals by the media will go a long way in removing the stigma and isolation associated with mental illness, bring the ill into the ambit of treatment, and improve their integration into society. This level of reporting can only be reached with considerable effort. We need to understand the media are geared towards sensationalism, and the facts regarding mental illness and the people affected by them are more nuanced.
