Early Signs and Symptoms
Understanding the early signs and symptoms of autism is essential for timely intervention. Autism Spectrum Disorder (ASD) is characterized by a range of symptoms that often manifest in early childhood, although they may not be fully noticeable until social demands exceed a child's capabilities.
Manifestation of Autism Signs
Symptoms of autism are evident during the early developmental period but may be subtle initially. Clinicians often look for the following early signs:
The following table summarizes common early signs of autism:

Varied Onset of Autism Symptoms
The onset of autism symptoms can vary significantly from child to child. For some, symptoms appear as early as infancy, while others may show signs later during their developmental years. Early symptoms might include a lack of response to their name by 12 months or minimal joint attention skills. As children grow, social demands can highlight these deficits.
The Centers for Disease Control and Prevention (CDC) states that most children are first evaluated for ASD by age 4; however, diagnosis may occur even later. Early diagnosis is vital for optimizing developmental outcomes. The prevalence of ASD is reported to be 1 in 54 among 8-year-olds in the U.S., with males diagnosed four times more frequently than females, which may point to genetic and diagnostic disparities [2].

Screening and Diagnosis
Understanding the importance of early detection in autism can significantly influence outcomes for children. Early screening and diagnosis play crucial roles in facilitating timely interventions.
Importance of Early Screening
Early screening is vital for identifying Autism Spectrum Disorder (ASD) as it allows for prompt intervention, which can alter the developmental trajectory for children on the spectrum. Symptoms of autism must be observable in the early developmental period, although they might not become fully noticeable until social demands exceed a child's capacities or are masked by learned behaviors later in life.
Timely diagnosis enables access to tailored therapies and support, helping children acquire essential skills for communication and socialization. Delays in diagnosis can lead to missed growth opportunities, emphasizing the need for vigilant monitoring of developmental milestones.
Age Recommendations for Screening
The American Academy of Pediatrics recommends that children undergo autism screening at specific ages. These recommendations include screening at 18 months and again at 24 months, alongside development and behavioral screenings during well-child visits at 9, 18, and 30 months [3].
Diagnosis is generally feasible by age two, although many children can be identified earlier. A summary of recommended screening ages is detailed in the table below:

Significance of Developmental Milestones
Developmental milestones serve as critical markers for assessing a child's growth and identifying potential red flags for autism. Most children with autism are diagnosed by the age of three, making the monitoring of early milestones essential [4].
Parents and caregivers should be attentive to social and communication milestones. For instance, regression in skills such as responding to one's name or making eye contact should prompt immediate evaluation for autism [5]. Tracking developmental progress can help guide the appropriate steps for intervention.
Engaging with healthcare professionals regarding milestones can enhance understanding and support for children suspected of having autism. For further insights, resources like the challenges in autism diagnosis can provide additional context. Early intervention services are crucial for improving developmental outcomes, making proactive screening and monitoring all the more critical.
Factors Affecting Diagnosis
Understanding the factors that influence the diagnosis of autism is essential for improving early detection and intervention. This section highlights the disparities across gender, race, and the role of genetic factors in autism diagnosis.
Gender Disparities in Diagnosis
Research indicates that autism is diagnosed more frequently in boys than in girls. The ratio of diagnosed cases is approximately four boys for every girl. This disparity may be attributed to multiple factors, including behavioral differences and diagnostic criteria that may overlook signs in females. Girls often exhibit less overt symptoms and may develop coping strategies that mask their difficulties, leading to later diagnoses.

Racial Disparities in Diagnosis
Racial disparities also play a significant role in autism diagnosis. Studies show that Black children, particularly girls, are diagnosed later than their White counterparts. This delay can result from various factors, including cultural perceptions of autism and access to healthcare services. Black children experience a higher incidence of autism spectrum disorder; however, they often encounter barriers to timely diagnosis and treatment [4].

Impact of Genetic Factors
Genetic factors play a crucial role in autism spectrum disorder (ASD). Certain genetic variations and mutations have been linked directly to autism, with some cases classified as monogenic, meaning they result from variations in a single gene. Conditions such as fragile X syndrome, tuberous sclerosis, and Rett syndrome show a higher risk of ASD due to specific genetic mutations. This understanding of genetic influences not only helps clarify diagnostic guidelines but also opens avenues for personalized treatment strategies.
