A cognitive intervention is a form of psychological intervention, a technique and therapy practised in counselling. It describes a myriad of approaches to therapy that focus on addressing psychological distress at a cognitive level. It is also associated with cognitive therapy, which focuses on the thought process and the manner by which emotions have bearing on the cognitive processes and structures. [1] The cognitive intervention forces behavioral change. [2] Counselors adopt different technique level to suit the characteristic of the client. For instance, when counseling adolescents, a more advanced strategy is adopted than the intervention used in children. [3] Before the intervention, an initial cognitive assessment is also conducted to cover the concerns of the cognitive approach, which cover the whole range of human expression - thought, feeling, behavior, and environmental triggers. [4]
The various types of cognitive interventions are practiced in cognitive psychology. [5]
Cognitive intervention focuses on addressing and changing beliefs and attitudes as well as improving cognition. Notably, a common domain of interventions is the inspection of past experiences that led to formations of certain beliefs and attitudes. Retrospection is most often used to change how past events/experiences are perceived by the individual. [6] The purpose of addressing past experiences is to address the root of the psychological distress and, by doing so, redirect thoughts and relieve distress. Another common domain is mental stimulation to avoid the decay of neural pathways. [7] This generally focuses on creating new neural pathways and/or stimulating existing pathways. [7] Cognitive interventions assume that thought processes can, to some extent, be controlled and changed by the individual. Generally, all cognitive interventions focus on exercising the mind to think differently.
One of the earliest uses of cognitive interventions was by Aaron T. Beck and colleagues. Beck's "cognitive theory of depression" focused on addressing beliefs that a person holds that makes them being more susceptible to depression. [8] Part of Beck's cognitive theory focused on the cognitive triad to model belief systems. These beliefs can be about themselves, others, or the world around them. [8] For instance, one harmful belief is never being good enough which can lead to self-deprecation and lead to increased vulnerability to depression. Beck developed cognitive therapies to address and change these beliefs in order to help manage depression. Cognitive therapy consists of a series of sessions that aim to provide depressed patients with "cognitive and behavioural skills" to cope with depression. [8]
Beck's cognitive therapy was further developed for clinical uses to address a broad spectrum of mental illnesses. Beck's cognitive theory of depression was extended to address general anxiety disorder, personality disorders and more. [9] Cognitive therapies developed to address mental disorders focused on changing maladaptive beliefs that modify people's perception of self and well as experience of their environment.
Modern use of cognitive interventions has extended beyond addressing beliefs to treating a broad range of psychological problems at a cognitive level.
Cognitive interventions are applied in both clinical and non-clinical settings. The cognitive intervention strategy differs depending on the application but follows the same general framework. The strategies used depend on the target of the intervention.
Cognitive interventions are a non-pharmacological/psychological method of approaching dementia as well as mild cognitive impairment. The three approaches to cognitive interventions for dementia were developed in 2003 by Clare and colleagues. [7] The three approaches were created for the purpose of using cognitive interventions to address Alzheimer's disease (AD), and it has been widely used to address AD and different forms of dementia. [10] They defined a conceptual framework that categorised three approaches to cognitive interventions. The three approaches have different purposes and underlying assumptions.
There is a general pattern of cognitive decline as people age, and one notable aspect of decline is memory. [11] Specifically, memory performance declines in the older adult population as well as their memory self-efficacy. In other words, older adults have decreasing memory functions as well as a loss of confidence in their abilities to "use memory effectively". [11] However, due to adult neurogenesis, people are capable of enhancing their cognitive abilities throughout their life. [11] Thus numerous cognitive interventions models were developed to improve memory performance and increase memory self-efficacy. These models have been tested for their significance in improving cognitive functioning. Some notable models are:
Current evidence suggests that cognition-based interventions do improve mental performance (i.e. memory, executive function, attention, and speed) in older adults and people with mild cognitive impairment. [14] Especially, immediate and delayed verbal recall resulted in higher performance gains from memory training.
The use of cognitive interventions to address mental disorders is controversial and have had mixed results. Cognitive intervention programs have shown to be ineffective to treat certain conditions and therefore puts in the question the scope of applications for cognitive interventions.
Aphasia is an inability to comprehend or formulate language because of damage to specific brain regions. The major causes are stroke and head trauma; prevalence is hard to determine but aphasia due to stroke is estimated to be 0.1–0.4% in the Global North. Aphasia can also be the result of brain tumors, brain infections, or neurodegenerative diseases.
Cognitive behavioral therapy (CBT) is a psycho-social intervention that aims to reduce symptoms of various mental health conditions, primarily depression and anxiety disorders. CBT focuses on challenging and changing cognitive distortions and their associated behaviors to improve emotional regulation and develop personal coping strategies that target solving current problems. Though it was originally designed to treat depression, its uses have been expanded to include the treatment of many mental health conditions, including anxiety, substance use disorders, marital problems, and eating disorders. CBT includes a number of cognitive or behavioral psychotherapies that treat defined psychopathologies using evidence-based techniques and strategies.
Dementia is a disorder which manifests as a set of related symptoms, which usually surfaces when the brain is damaged by injury or disease. The symptoms involve progressive impairments in memory, thinking, and behavior, which negatively affects a person's ability to function and carry out everyday activities. Aside from memory impairment and a disruption in thought patterns, the most common symptoms include emotional problems, difficulties with language, and decreased motivation. The symptoms may be described as occurring in a continuum over several stages. Consciousness is not affected. Dementia ultimately has a significant effect on the individual, caregivers, and on social relationships in general. A diagnosis of dementia requires the observation of a change from a person's usual mental functioning and a greater cognitive decline than what is caused by normal aging.
Dementia with Lewy bodies (DLB) is a type of dementia characterized by changes in sleep, behavior, cognition, movement, and regulation of automatic bodily functions. Memory loss is not always an early symptom. The disease worsens over time and is usually diagnosed when cognitive impairment interferes with normal daily functioning. Together with Parkinson's disease dementia, DLB is one of the two Lewy body dementias. It is a common form of dementia, but the prevalence is not known accurately and many diagnoses are missed. The disease was first described by Kenji Kosaka in 1976.
Donepezil, sold under the brand name Aricept among others, is a medication used to treat dementia of the Alzheimer's type. It appears to result in a small benefit in mental function and ability to function. Use, however, has not been shown to change the progression of the disease. Treatment should be stopped if no benefit is seen. It is taken by mouth or via a transdermal patch.
The primary goals of stroke management are to reduce brain injury and promote maximum patient recovery. Rapid detection and appropriate emergency medical care are essential for optimizing health outcomes. When available, patients are admitted to an acute stroke unit for treatment. These units specialize in providing medical and surgical care aimed at stabilizing the patient's medical status. Standardized assessments are also performed to aid in the development of an appropriate care plan. Current research suggests that stroke units may be effective in reducing in-hospital fatality rates and the length of hospital stays.
Art therapy is a distinct discipline that incorporates creative methods of expression through visual art media. Art therapy, as a creative arts therapy profession, originated in the fields of art and psychotherapy and may vary in definition.
Cognitive disorders (CDs), also known as neurocognitive disorders (NCDs), are a category of mental health disorders that primarily affect cognitive abilities including learning, memory, perception, and problem solving. Neurocognitive disorders include delirium, mild neurocognitive disorders, and major neurocognitive disorder (previously known as dementia). They are defined by deficits in cognitive ability that are acquired (as opposed to developmental), typically represent decline, and may have an underlying brain pathology. The DSM-5 defines six key domains of cognitive function: executive function, learning and memory, perceptual-motor function, language, complex attention, and social cognition.
Age-related memory loss, sometimes described as "normal aging", is qualitatively different from memory loss associated with types of dementia such as Alzheimer's disease, and is believed to have a different brain mechanism.
Brain training is a program of regular activities purported to maintain or improve one's cognitive abilities. The phrase “cognitive ability” usually refers to components of fluid intelligence such as executive function and working memory. Cognitive training reflects a hypothesis that cognitive abilities can be maintained or improved by exercising the brain, analogous to the way physical fitness is improved by exercising the body. Cognitive training activities can take place in numerous modalities such as cardiovascular fitness training, playing online games or completing cognitive tasks in alignment with a training regimen, playing video games that require visuospatial reasoning, and engaging in novel activities such as dance, art, and music.
Mild cognitive impairment (MCI) is a neurocognitive disorder which involves cognitive impairments beyond those expected based on an individual's age and education but which are not significant enough to interfere with instrumental activities of daily living. MCI may occur as a transitional stage between normal aging and dementia, especially Alzheimer's disease. It includes both memory and non-memory impairments. The cause of the disorder remains unclear, as well as both its prevention and treatment, with some 50 percent of people diagnosed with it going on to develop Alzheimer's disease within five years. The diagnosis can also serve as an early indicator for other types of dementia, although MCI may remain stable or even remit.
Reminiscence therapy is used to counsel and support older people, and is an intervention technique with brain-injured patients and those who appear to have "Alzheimer's and other forms of cognitive disease."
Pseudodementia is a condition where mental cognition can be temporarily decreased. The term pseudodementia is applied to the range of functional psychiatric conditions such as depression and schizophrenia, that may mimic organic dementia, but are essentially reversible on treatment. Pseudodementia typically involves three cognitive components: memory issues, deficits in executive functioning, and deficits in speech and language. Specific cognitive symptoms might include trouble recalling words or remembering things in general, decreased attentional control and concentration, difficulty completing tasks or making decisions, decreased speed and fluency of speech, and impaired processing speed. People with pseudodementia are typically very distressed about the cognitive impairment they experience. There are two specific treatments that have been found to be effective for the treatment of depression, and these treatments may also be beneficial in the treatment of pseudodementia. Cognitive behavioral therapy (CBT) involves exploring and changing thought patterns and behaviors in order to improve one's mood. Interpersonal therapy focuses on the exploration of an individual's relationships and identifying any ways in which they may be contributing to feelings of depression. Some antidepressant drugs have also been found to alleviate cognitive deficits arising from depression; in particular, the novel SSRI vortioxetine has been studied for treating pseudodementia.
Psychological therapies for dementia are starting to gain some momentum. Improved clinical assessment in early stages of Alzheimer's disease and other forms of dementia, increased cognitive stimulation of the elderly, and the prescription of drugs to slow cognitive decline have resulted in increased detection in the early stages. Although the opinions of the medical community are still apprehensive to support cognitive therapies in dementia patients, recent international studies have started to create optimism.
Alzheimer's disease (AD) is a neurodegenerative disease that usually starts slowly and progressively worsens. It is the cause of 60–70% of cases of dementia. The most common early symptom is difficulty in remembering recent events. As the disease advances, symptoms can include problems with language, disorientation, mood swings, loss of motivation, self-neglect, and behavioral issues. As a person's condition declines, they often withdraw from family and society. Gradually, bodily functions are lost, ultimately leading to death. Although the speed of progression can vary, the typical life expectancy following diagnosis is three to nine years.
Cognitive remediation is designed to improve neurocognitive abilities such as attention, working memory, cognitive flexibility and planning, and executive functioning which leads to improved psychosocial functioning.
Sensory stimulation therapy (SST) is an experimental therapy that aims to use neural plasticity mechanisms to aid in the recovery of somatosensory function after stroke or cognitive ageing. Stroke and cognitive ageing are well known sources of cognitive loss, the former by neuronal death, the latter by weakening of neural connections. SST stimulates a specific sense at a specific frequency. Research suggests that this technique may reverse cognitive ageing by up to 30 years, and may selectively improve or impair two point discrimination thresholds.
PTSD or post-traumatic stress disorder, is a psychiatric disorder characterised by intrusive thoughts and memories, dreams or flashbacks of the event; avoidance of people, places and activities that remind the individual of the event; ongoing negative beliefs about oneself or the world, mood changes and persistent feelings of anger, guilt or fear; alterations in arousal such as increased irritability, angry outbursts, being hypervigilant, or having difficulty with concentration and sleep.
The neurobiological effects of physical exercise are numerous and involve a wide range of interrelated effects on brain structure, brain function, and cognition. A large body of research in humans has demonstrated that consistent aerobic exercise induces persistent improvements in certain cognitive functions, healthy alterations in gene expression in the brain, and beneficial forms of neuroplasticity and behavioral plasticity; some of these long-term effects include: increased neuron growth, increased neurological activity, improved stress coping, enhanced cognitive control of behavior, improved declarative, spatial, and working memory, and structural and functional improvements in brain structures and pathways associated with cognitive control and memory. The effects of exercise on cognition have important implications for improving academic performance in children and college students, improving adult productivity, preserving cognitive function in old age, preventing or treating certain neurological disorders, and improving overall quality of life.
For patients with Alzheimer's disease, music therapy provides a beneficial interaction between a patient and an individualized musical regimen and has been shown to increase cognition and slow the deterioration of memory loss. Music therapy is a clinical and evidence-based intervention that involves music in some capacity and includes both a participant and a music therapist who have completed an accredited music therapy program.
