Effective Speech Therapy: Hire A Specialist For Stroke Recovery

A stroke occurs when the blood flow within the brain becomes compromised, causing brain cells to die as they are deprived of oxygen and essential nutrients. This can lead to a variety of disabilities, including problems with speech and language. Speech therapy can help stroke survivors with these issues by identifying their difficulties and providing appropriate treatment. Speech therapists, also known as speech-language pathologists, are healthcare professionals who assess, diagnose, and treat communication, speech, and swallowing disorders in both children and adults. They work in various settings, including hospitals, clinics, rehabilitation centres, schools, and research facilities, often in collaboration with other professionals such as teachers, doctors, and social workers. When hiring a speech therapist, managers look for empathetic and patient communicators with excellent interpersonal skills. If you or a loved one are experiencing speech problems after a stroke, seeking the help of a licensed speech therapist can be beneficial to improve communication and language skills.

Aphasia: difficulty speaking, reading, writing or understanding others

Aphasia is a common language disorder that affects one-third of stroke survivors. It impacts an individual's ability to speak, read, write and understand others. Aphasia occurs when the brain can no longer understand or use language, and it can manifest in various ways. For instance, some people with aphasia can understand language but cannot speak, while others may speak without making sense, jumbling words or making up new ones.

The condition is caused by strokes in the left side of the brain, which controls speech and language. Aphasia can also be categorised into different types, depending on the area of the brain affected. These include:

• Broca’s aphasia (expressive aphasia): difficulty with spoken and written expression.
• Anomic aphasia: difficulty with word retrieval, leading to slow and halting speech.
• Wernicke’s aphasia (receptive aphasia): difficulty understanding speech and producing meaningful responses; those affected can speak long, fluent sentences that don't make sense.
• Conduction aphasia: difficulty repeating words or phrases.
• Global aphasia: difficulties with both speech production and comprehension.

While these are the most common types of aphasia, there are other forms, such as transcortical sensory aphasia, transcortical motor aphasia, and mixed transcortical aphasia.

Aphasia does not affect a person's intelligence. Stroke survivors with aphasia remain mentally alert, even though they may experience challenges in expressing themselves or understanding others.

Treatment for aphasia typically involves speech and language therapy, where individuals work with speech-language pathologists or speech therapists to improve their communication skills. These specialists help individuals improve their speech, reading and writing abilities and explore alternative communication methods, such as gestures or electronic devices.

While communication problems due to aphasia can improve over time with treatment, the rate of recovery varies for each person. Most improvements occur within the first three to six months, but people continue to recover for months or even years.

Apraxia: trouble coordinating muscles for speech

Apraxia of speech is a common condition following a stroke. It occurs when the brain struggles to tell the muscles how to move when speaking, resulting in difficulty with speech-related motor abilities. This condition can affect an individual's ability to express their needs, connect with others, and return to work.

People with apraxia of speech know what they want to say, but their brain struggles to send the right messages to the muscles involved in speaking, such as the tongue and lips. This can lead to difficulty producing the desired sounds needed to speak specific words. For example, they may say "chicken" instead of "kitchen" or use entirely different words.

Symptoms of apraxia of speech include difficulty producing or repeating desired sounds, inconsistent speech errors, and slow or absent speech. Individuals with apraxia may make groping movements with their tongue and lips as they try to articulate words, and their speech may be characterised by long pauses and altered rhythm or tone.

Treatment for apraxia of speech focuses on helping the muscles work together to produce speech. This may include exercises to improve the accuracy of sound production, as well as increasing the speed and rhythm of speech. Treatment may also involve practicing with words and sentences that gradually increase in length and complexity.

While recovery from apraxia of speech can be challenging, it is possible to improve with consistent practice and the help of a speech-language pathologist or therapist.

Dysarthria: weakness or paralysis of muscles used for speaking

Dysarthria is a motor speech disorder that arises from damage to the nervous system, causing the muscles used for speech to become paralysed or weakened. This makes it difficult to control the tongue, voice box, lips, and jaw, resulting in slurred speech. It is important to distinguish dysarthria from aphasia, which is the medical term for communication problems arising from stroke. Aphasia affects the ability to understand or produce language, whereas dysarthria affects the motor skills required for speech.

Dysarthria can be developmental or acquired. Developmental dysarthria occurs due to brain damage during fetal development or at birth and is more common in children. Acquired dysarthria happens later in life due to brain damage from a stroke, brain tumour, or Parkinson's disease, and is more common in adults.

There are six categories of dysarthria, depending on the specific part of the nervous system affected: flaccid, spastic, ataxic, hypokinetic, hyperkinetic, and mixed dysarthria. Flaccid dysarthria results from damage to the lower motor neurons, leading to breathy and nasal-sounding speech. Spastic dysarthria arises from damage to the upper neurons in the brain and causes strained or harsh-sounding speech. Ataxic dysarthria results from damage to the cerebellum, leading to difficulties with vowel and consonant pronunciation. Hypokinetic dysarthria is caused by damage to the basal ganglia and is associated with slow, monotone, and rigid-sounding speech. Hyperkinetic dysarthria also arises from damage to the basal ganglia and is characterised by fast and unpredictable speech. Mixed dysarthria involves a combination of two or more of the other types.

Treatment for dysarthria often involves speech therapy, where individuals learn exercises to strengthen their tongue, lips, and jaw muscles. They also learn strategies for speaking louder and more clearly, such as taking fuller breaths and slowing down their speech. Nonverbal communication techniques, such as gestures or writing, may be taught as well. In severe cases, individuals may need devices to aid communication, such as letter or picture boards or special computers with keyboards and message displays.

Dysphonia: vocal chord muscles are weak or paralysed

Communication problems are very common after a stroke, with over half of stroke survivors experiencing issues with speech. When a stroke affects speech or language, it can impact the ability to communicate effectively due to changes in cognitive language skills or speech-related motor abilities.

Dysphonia is a voice disorder that occurs when the muscles around the larynx (voice box) are so tight during speech that the voice box does not work efficiently. This can be caused by an injury to the vagus or recurrent laryngeal nerves, which are critical for normal speech production. There are two types of dysphonia:

• Vocal Cord Paralysis: A complete loss of nerve input to the vocal folds, resulting in no movement of the vocal cord.
• Vocal Fold Paresis: A partial loss of input to the nerve of the vocal fold, causing reduced function and movement.

Symptoms of dysphonia include a breathy, hoarse, or rough voice, tightness and muscle aches in the throat, a strained or tight voice, sudden breaks or fading of the voice, and a frequent need to clear the throat. It is often hard to diagnose and can mimic other illnesses. An appropriate diagnosis requires a thorough examination by a team of experienced voice specialists.

Treatments for dysphonia include voice therapy, which is the most common treatment and may include resonant voice techniques and massage. Botox injections may also be used alongside voice therapy to stop voice box spasms. Early identification of the cause is critical, as treatments are dictated by the root cause.

Cognitive difficulties: trouble paying attention, understanding or speaking complex sentences

Cognitive difficulties are common after a stroke, affecting around one-third of survivors. These difficulties can manifest in several ways, including trouble paying attention, understanding or speaking complex sentences, problems with memory, thinking and judgement, and issues with planning and problem-solving.

The impact of cognitive difficulties on communication can be significant, making it hard for stroke survivors to connect with others. They may struggle to express their needs and desires, understand what others are saying, or have a conversation. This can lead to feelings of isolation and an increased risk of depression.

Cognitive difficulties after a stroke are caused by damage to specific areas of the brain. This damage can affect the brain's ability to understand, organise and store information, resulting in challenges with cognition. Different parts of the brain work together to produce cognitive skills, so damage to one area can have a ripple effect on various functions.

Treatment for cognitive difficulties focuses on managing the problems rather than curing them. Occupational therapists play a crucial role in helping patients develop coping strategies, such as using aids like diaries, labels and reminders. In more severe or specific cases, patients may be referred to a clinical neuropsychologist or clinical psychologist for further assessment and support.

The road to recovery from cognitive difficulties is often long, and improvement can continue for months or even years. While most recovery occurs in the first few months, ongoing rehabilitation and support are essential for optimising outcomes. Speech and language therapy, as well as consistent practice, are key components of the recovery journey.
