Introduction
Autism spectrum disorder (ASD) and autism are not the same. Autism is the core type of autism spectrum disorder, which has a broader scope and includes a range of related conditions with varying severity and diverse presentations. Accurately distinguishing between the two helps ensure a precise understanding of the condition. Whether it is classic autism or other disorders within the spectrum, intervention plans should be tailored according to individual characteristics.

Autism spectrum disorder (ASD) and autism are not the same. Autism is the core type of autism spectrum disorder, which has a broader scope and includes a range of related conditions with varying severity and manifestations. A detailed analysis is as follows:

Autism typically refers to classic autism, characterized primarily by impairments in social communication, restricted interests, and repetitive, stereotyped behaviors. Symptoms are relatively obvious and representative. In contrast, autism spectrum disorder is an umbrella term that includes not only classic autism but also Asperger syndrome, pervasive developmental disorder-not otherwise specified (PDD-NOS), and others. These subtypes differ in aspects such as social ability and language development; some individuals may have relatively strong language skills but still experience social challenges. The key difference lies in the inclusivity of the spectrum—ASD emphasizes the continuity of symptoms and individual variability, encompassing everything from mild social difficulties to severe functional impairments.

Accurately distinguishing between these two concepts helps ensure a precise understanding of the condition. Whether it is classic autism or another disorder within the spectrum, intervention plans should be tailored according to individual characteristics. By addressing each patient's unique needs through professional training and family support, we can help improve their daily living skills and social adaptability.

Will the children of individuals with autism have strabismus?
Autism is a neurodevelopmental disorder. Although it is associated with genetic factors, it is not a directly inherited disease. Its genetic mechanism involves multiple genes, epigenetic factors, and interactions with the environment, and cannot be simply attributed to either parent. Strabismus, on the other hand, is an ophthalmological condition whose causes include genetic factors, abnormalities in neuromuscular development, and refractive errors. Some strabismus patients show familial clustering.

Is it good for autistic children to take lactulose?
Children with autism spectrum disorder often have delayed intestinal development and poor development of the enteric nervous system, making them prone to functional constipation. Lactulose, as an osmotic laxative, softens stool and relieves constipation by modulating gut microbiota and acidifying the intestinal environment to stimulate peristalsis. Lactulose increases bowel movement frequency in children with chronic constipation and serves as an adjunctive treatment for constipation caused by reduced intestinal motility in autistic children.

Can abnormal brain evoked potentials in children cause autism?
Under normal circumstances, abnormalities in somatosensory evoked potentials in children's brain evoked potential tests do not directly cause autism. In daily life, it is important to create an inclusive and warm environment for the child, engage in frequent interaction and communication, encourage participation in group activities, and promote the development of social skills. Maintain a regular schedule for sleep and meals, ensure balanced nutrition, and support healthy neurological development. Address abnormalities in somatosensory evoked potentials accordingly.

Is there a direct relationship between dysmyelination and autism?
In general, hypomyelination and autism are not directly related, but there may be an association in some cases. A regular and gentle environment should be provided in daily life, avoiding frequent changes that could cause discomfort. Simple cognitive and social guidance should be developed according to the individual's abilities, with emphasis on using play and interactive activities to help establish communication.

Will autistic individuals be the same as neurotypical people when they grow up?
In general, whether individuals with autism will develop like neurotypical people as they grow up depends on a comprehensive assessment of the severity of their condition, the effectiveness of interventions and treatments, and individual developmental differences. Throughout their development, it is important to provide consistent, patient guidance, respect individual differences, and avoid forcing changes to their unique behavioral patterns. An inclusive social environment should be created, and participation in suitable group activities should be encouraged.

What happens if someone has social loneliness for a long time?
Prolonged outward-directed loneliness typically leads to emotional exhaustion, social avoidance, confusion in self-identity, somatic symptoms, and difficulties in forming intimate relationships. Emotional exhaustion arises from maintaining an active social life while experiencing inner loneliness, resulting in excessive depletion of emotional energy. Individuals may appear enthusiastic and cheerful on the surface, yet privately feel fatigued, empty, or even emotionally numb.

What is the normal score for the Childhood Autism Rating Scale (CARS)?
A total score of ≤14 on the Childhood Autism Rating Scale (CARS) falls within the normal range. A score above 14 suggests the possible presence of autism-related behavioral characteristics, with higher scores indicating a greater likelihood. However, this scale is only a screening tool and cannot serve as a basis for diagnosis. If the scale results are abnormal or if signs such as impaired social communication or repetitive behaviors are observed, it is recommended to seek medical evaluation promptly.

Is ADHD a type of autism?
ADHD is not a form of autism; the two are distinct neurodevelopmental disorders that differ in core symptoms, underlying mechanisms, and intervention approaches. However, some individuals may exhibit features of both conditions. In daily life, if significant behavioral abnormalities are observed in children, timely professional evaluation should be sought, and individualized intervention plans should be developed based on the specific diagnosis.
