Through Alternative medicine, Alzheimer's disease and Mood disorder

Music therapy is a broad field, using music-based experiences to address client needs in one or more domains of human functioning: cognitive, academic, emotional/psychological, behavioral, communication, social, physiological (sensory, motor, pain, neurological and other physical systems), spiritual, or aesthetics. Music experiences are strategically designed to use the elements of music for therapeutic effects, including melody, harmony, key, mode, meter, rhythm, pitch/range, duration, timbre, form, texture, and instrumentation.

Some common music therapy practices include developmental work (communication, motor skills, etc.) with individuals with special needs, songwriting and listening in reminiscence, orientation work with the elderly, processing and relaxation work, and rhythmic brainwave entrainment for physical rehabilitation in stroke survivors. Music therapy is used in medical hospitals, cancer centers, schools, alcohol and drug recovery programs, psychiatric hospitals, nursing homes, and correctional facilities.

Music therapy is distinctive from musopathy, which relies on a more generic and non-cultural approach based on neural, physical, and other responses to the fundamental aspects of sound. Music therapy might also incorporate practices from sound healing, also known as sound immersion or sound therapy, which focuses on sound rather than song. Sound healing describes the use of vibrations and frequencies for relaxation, meditation, and other claimed healing benefits. Unlike music therapy, sound healing is unregulated and an alternative therapy.

Music therapists use their techniques to help their patients in many areas, ranging from stress relief before and after surgeries to neuropathologies such as Alzheimer's disease. Studies on people diagnosed with mental health disorders such as anxiety, depression, and schizophrenia have associated some improvements in mental health with music therapy. However, in many countries, including the United States, music therapists do not diagnose, so diagnosing mental disorders would not be within their scope of practice. The National Institute for Health and Care Excellence (NICE) has claimed that music therapy is an effective method in helping people with mental health issues, and more should be done to offer those in need of this type of help.

Uses

Children and adolescents

Music therapy may be suggested for adolescent populations to help manage disorders usually diagnosed in adolescence, such as mood and anxiety disorders and eating disorders, or unpleasant behaviors, including suicide attempts, withdrawal from family, social isolation from peers, aggression, running away, and substance abuse. Goals in treating adolescents with music therapy, especially for those at high risk, often include increased recognition and awareness of emotions and moods, improved decision-making skills, opportunities for creative self expression, decreased anxiety, increased self-confidence, improved self-esteem, and better listening skills.

There is some evidence that, when combined with other types of rehabilitation, music therapy may contribute to the success rate of sensorimotor, cognitive, and communicative rehabilitation. For children and adolescents with major depressive or anxiety disorders, there is moderate to low quality evidence that music therapy added to the standard treatment, may reduce internalizing symptoms, and may be more effective than treatment without music therapy.

Premature infants

Premature infants are those born at 37 weeks after conception or earlier. Offering musical therapy to premature infants while they are in the neonatal intensive care unit (NICU) aims to both mask unwanted auditory stimuli, stimulate infant development, and promote a calm environment for families. While there are no reported adverse effects from music therapy, the evidence supporting music therapy's beneficial effects for infants is weak as many of the clinical trials that have been performed either had mixed results or were poorly designed. There is no strong evidence to suggest that music therapy improves an infant's oxygen therapy, improves sucking, or improves development when compared to usual care. There is some weaker evidence that music therapy may decrease an infants' heart rate. There is no evidence to indicate that music therapy reduces anxiety in parents of preterm infants in the NICU or information to understand what type of music therapy may be more beneficial or how for how long.

Medical disorders

Music may both motivate and provide a sense of distraction. Rhythmic stimuli has been found to help balance training for those with a brain injury.

Singing is a form of rehabilitation for neurological impairments. Neurological impairments following a brain injury can be in the form of apraxia – loss to perform purposeful movements, dysarthria, muscle control disturbances (due to damage of the central nervous system), aphasia (defect in expression causing distorted speech), or language comprehension. It is shown that patients with schizophrenia have altered feeling on major and minor chord. Singing training has been found to improve lung, speech clarity, and coordination of speech muscles, thus, accelerating rehabilitation of such neurological impairments. For example, melodic intonation therapy is the practice of communicating with others by singing to enhance speech or increase speech production by promoting socialization, and emotional expression. After a stroke, music therapy may be a useful tool for the recovery of motor skills. Listening to music may improve heart rate, respiratory rate, and blood pressure in those with coronary heart disease (CHD). In addition, there is tentative evidence that music interventions led by a trained music therapist may have positive effects on psychological and physical outcomes in adults with cancer. The effectiveness of music therapy for children with cancer is not known.

Autism

Music may help people with autism hone their motor and attention skills as well as healthy neurodevelopment of socio-communication and interaction skills. Music therapy may also contribute to improved selective attention, speech production, and language processing and acquisition in people with autism. Music therapy may benefit the family as a whole. Some family members of children with autism claim that music therapy sessions have allowed their child to interact more with the family and the world. Music therapy is also beneficial in that it gives children an outlet to use outside of the sessions. Some children after participating in music therapy may want to keep making music long after the sessions end.

Dementia

Like many of the other disorders mentioned, some of the most common significant effects of dementia can be seen in social behaviors, leading to improvements in interaction, conversation, and other such skills. A study of over 330 subjects showed that music therapy produces highly significant improvements in social behaviors, overt behaviors like wandering and restlessness, reductions in agitated behaviors, and improvements to cognitive defects, measured with reality orientation and face recognition tests. The effectiveness of the treatment seems to be strongly dependent on the patient and the quality and length of treatment.

A meta-study examined the proposed neurological mechanisms behind music therapy's effects on these patients. Many authors suspect that music has a soothing effect on the patient by affecting how noise is perceived: music renders noise familiar, or buffers the patient from overwhelming or extraneous noise in their environment. Others suggest that music acts like a mediator for social interactions, providing a vessel through which to interact with others without requiring much cognitive load.

Aphasia

Broca's aphasia, or non-fluent aphasia, is a language disorder caused by damage to Broca's area and surrounding regions in the left frontal lobe. Those with non-fluent aphasia are able to understand language fairly well, they struggle with language production and syntax.

Neurologist Oliver Sacks studied neurological oddities in people, trying to understand how the brain works. He concluded that people with some type of frontal lobe damage often "produced not only severe difficulties with expressive language (aphasia) but a strange access of musicality with incessant whistling, singing and a passionate interest in music. For him, this was an example of normally suppressed brain functions being released by damage to others". Sacks had a genuine interest in trying to help people affected with neurological disorders and other phenomena associated with music, and how it can provide access to otherwise unreachable emotional states, revivify neurological avenues that have been frozen, evoke memories of earlier, lost events or states of being and attempts to bring those with neurological disorders back to a time when the world was much richer for them. He was a firm believer that music has the power to heal.

Melodic intonation therapy (MIT), developed in 1973 by neurological researchers Sparks, Helm and Albert, is a method used by music therapists and speech–language pathologists to help people with communication disorders caused by damage to the left hemisphere of the brain by engaging the singing abilities and possibly engaging language-capable regions in the undamaged right hemisphere.

While unable to speak fluently, patients with non-fluent aphasia are often able to sing words, phrases, and even sentences they cannot express otherwise. MIT harnesses the singing ability of patients with non-fluent aphasia as a means to improve their communication. Although its exact nature depends on the therapist, in general MIT relies on the use of intonation (the rising and falling of the voice) and rhythm (beat/speed) to train patients to produce phrases verbally. In MIT, common words and phrases are turned into melodic phrases, generally starting with two step sing-song patterns and eventually emulating typical speech intonation and rhythmic patterns. A therapist will usually begin by introducing an intonation to their patient through humming. They will accompany this humming with a rhythm produced by the tapping of the left hand. At the same time, the therapist will introduce a visual stimuli of the written phrase to be learned. The therapist then sings the phrase with the patient, and ideally the patient is eventually able to sing the phrase on their own. With much repetition and through a process of "inner-rehearsal" (practicing internally hearing one's voice singing), a patient may eventually be able to produce the phrase verbally without singing. As the patient advances in therapy, the procedure can be adapted to give them more autonomy and to teach them more complex phrases. Through the use of MIT, a non-fluent aphasic patient can be taught numerous phrases which aid them to communicate and function during daily life.

The mechanisms of this success are yet to be fully understood. It is commonly agreed that while speech is lateralized mostly to the left hemisphere (for right-handed and most left-handed individuals), some speech functionality is also distributed in the right hemisphere. MIT is thought to stimulate these right language areas through the activation of music processing areas also in the right hemisphere Similarly, the rhythmic tapping of the left hand stimulates the right sensorimotor cortex to further engage the right hemisphere in language production. Overall, by stimulating the right hemisphere during language tasks, therapists hope to decrease dependence on the left hemisphere for language production.

While results are somewhat contradictory, studies have in fact found increased right hemispheric activation in non-fluent aphasic patients after MIT. This change in activation has been interpreted as evidence of decreased dependence on the left hemisphere. There is debate, however, as to whether changes in right hemispheric activation are part of the therapeutic process during/after MIT, or are simply a side effect of non-fluent aphasia. In hopes of making MIT more effective, researchers are continually studying the mechanisms of MIT and non-fluent aphasia.

Mental health

There is weak evidence to suggest that people with schizophrenia may benefit from the addition of music therapy along with their other standard treatment regime. Potential improvements include decreased aggression, fewer hallucinations and delusions, social functioning, and quality of life of people with schizophrenia or schizophrenia-like disorders. In addition, moderate-to-low-quality evidence suggests that music therapy as an addition to standard care improves mental state (including negative and general symptoms). Further research using standardized music therapy programs and consistent monitoring protocols are necessary to understand the effectiveness of this approach for adults with schizophrenia. Music therapy may be a useful tool for helping treat people with post-traumatic stress disorder; however, more rigorous empirical study is required.

For adults with depressive symptoms, there is some weak evidence to suggest that music therapy may help reduce symptoms, with recreative music therapy and guided imagery and music being superior to other methods in reducing depressive symptoms.

In the use of music therapy for adults, "music medicine", in which prerecorded music is treated like a medicine, may be employed. Music therapy may also use "receptive music therapy" using "music-assisted relaxation" and using images connecting to the music.

There is some discussion on the process of change facilitated by musical activities on mental wellness. Scholars proposed a six-dimensional framework, which contains emotional, psychological, social, cognitive, behavioral and spiritual aspects. Through conducting interview sessions with mental health service users (with mood disorders, anxiety disorders, schizophrenia and other psychotic disorders), their study showed the relevance of the six-dimensional framework.

Music therapy has been used to help bring improvements to mental health among people of all age groups. It has been used as far back as the 1830s. For example, the Hanwell Lunatic Asylum provided "music and movement sessions and musical performances" as well as "group and individual music therapy for patients with serious mental illness or emotional problems." Two main categories of music therapy were used in this study; analytic music therapy and Nordoff-Robbins music therapy. Analytic music therapy involves both words and music, while Nordoff-Robbins music therapy places great emphasis on assessing how clients react to music therapy and how the use of this type of therapy can be constantly altered and shifted to allow it to benefit the client the most.

Bereavement

The DSM-IV TR (Diagnostic and Statistical Manual of Mental Disorders) lists bereavement as a mental health diagnosis when the focus of clinical attention is related to the loss of a loved one and when symptoms of Major Depressive Disorder are present for up to two months. Music therapy models have been found to be successful in treating grief and bereavement.

Grief treatment for adolescents

Grief treatment is very valuable within the adolescent age group. Just as adults and the elderly struggle with grief from loss, relationship issues, job-related stress, and financial issues, so do adolescents also experience grief from disappointments that occur early on in life, however different these disappointing life events may be. For example, many people of adolescent age experience life-altering events such as parental divorce, trauma from emotional or physical abuse, struggles within school, and loss. If this grief is not acted upon early on through the use of some kind of therapy, it can alter the entire course of an adolescent's life. In one particular study on the impact of music therapy on grief management within adolescents used songwriting to allow these adolescents to express what they were feeling through lyrics and instrumentals. The results of the study Development of the Grief Process Scale through music therapy songwriting with bereaved adolescents demonstrate that in all of the treatment groups combined, the mean GPS (grief process scale) score decreased by 43%. The use of music therapy songwriting allowed these adolescents to become less overwhelmed with grief and better able to process it as demonstrated by the decrease in mean GPS score
