Summary
Apraxia of speech (AOS) is a motor speech disorder often linked to neurodegenerative diseases. This review covers AOS terminology, symptoms, brain correlates, and rehabilitation strategies for articulation and prosody.
Area of Science:
- Neurology
- Speech-Language Pathology
Background:
- Apraxia of speech (AOS) is a complex motor speech disorder.
- Historically, AOS has been a subject of debate among clinicians and researchers.
- Recent interest stems from its role as an early indicator of neurodegenerative conditions.
Purpose of the Study:
- To review the terminology, clinical features, and neuroanatomical basis of AOS.
- To discuss current motor programming models in relation to AOS.
- To summarize therapeutic approaches for AOS-related deficits.
Main Methods:
- Literature review of AOS.
- Analysis of clinical hallmarks and neuroanatomical correlates.
- Examination of motor programming theories and treatment strategies.
Main Results:
- AOS definition and diagnostic criteria clarified.
- Neuroanatomical correlates and implicated brain regions identified.
- Effective treatment strategies for articulation and prosody highlighted.
Conclusions:
- AOS is a distinct motor speech disorder with specific clinical and neurological underpinnings.
- Understanding motor programming is crucial for AOS diagnosis and treatment.
- Targeted rehabilitation can effectively address AOS-related speech impairments.

01:10Higher Mental Functions of the Brain: Language
Language is a system of communication that allows the expression of thoughts, ideas, and feelings. The brain processes language in both hemispheres.
Language formation and comprehension take place in the dominant hemisphere. The dominant hemisphere is responsible for understanding the meaning of spoken, written, or sign language, as well as the ability to communicate. For most people, the left hemisphere is the dominant one. The right hemisphere, then, gives tone and emotional context to the...

01:15Parkinson's Disease: Overview
Neurodegenerative disorders are progressive diseases that cause irreversible damage and loss to neurons in specific brain areas. Examples of these disorders include Parkinson's disease, Alzheimer's disease, Multiple Sclerosis (MS), and Amyotrophic Lateral Sclerosis (ALS). These disorders share characteristics such as proteinopathies, selective neuronal vulnerability, and a complex interplay between genetic and environmental factors. The primary therapeutic goal for these conditions is to...
01:24Prosopagnosia
Prosopagnosia, also known as face blindness, is the inability to recognize faces. In severe cases, individuals with prosopagnosia may not recognize close family members, including parents and spouses, by their faces. For instance, someone with prosopagnosia might walk past their child in a crowd, only realizing their mistake upon noticing their child's distinctive backpack or favorite jacket. Prosopagnosia specifically impairs facial recognition, while the recognition of other objects or...
01:22Language Development
Children master language quickly and with relative ease, supported by both biological predisposition and reinforcement. B. F. Skinner (1957) proposed that language is learned through reinforcement, while Noam Chomsky (1965) argued that language acquisition mechanisms are biologically determined.
The critical period for language acquisition suggests that the ability to acquire language is at its peak early in life. As people age, this proficiency decreases. Language development begins very...

01:19Autism Spectrum Disorder
Autism spectrum disorder (ASD) is a neurodevelopmental condition marked by persistent deficits in social communication and interaction alongside restrictive and repetitive behaviors or interests. ASD is sometimes accompanied by intellectual impairment.
These core symptoms manifest differently among individuals, ranging from mild to severe. The disorder's complexity extends beyond its clinical presentation, encompassing a diverse range of biological, cognitive, and sociocultural influences.

01:25Introduction to Language of Pathophysiology l
Pathophysiology investigates how biological mechanisms—typically starting at the cellular level—disrupt normal bodily functions. It bridges anatomy and physiology to explain the progression of disease. With this foundation, it is important to understand the following key terms used to describe disease processes: Diagnosis:The process of identifying a disease using clinical evaluation, including signs (objective evidence like rashes), symptoms (subjective experiences like pain), laboratory test...
