<h4 align="justify">Mental Retardation (Intellectual Disability)</h4>
<p align="justify"><b>Mental retardation</b>, now more commonly referred to as <b>intellectual disability (ID)</b>, is a developmental condition characterized by significant limitations in both intellectual functioning and adaptive behavior. These limitations manifest before the age of 18 and affect an individual&#8217;s ability to perform everyday activities and meet the expectations of their social and cultural environment.</p>
<h4 align="justify">Key Features of Intellectual Disability</h4>
<p align="justify"><b>Intellectual Functioning:</b></p>
<ol>
<li style="list-style-type: none;">
<ul>
<li>
<div align="justify"><b>Definition:</b> Intellectual functioning refers to general mental capacity, including learning, reasoning, problem-solving, and abstract thinking.</div>
</li>
<li>
<div align="justify"><b>Assessment:</b> It is typically assessed using standardized intelligence tests. An IQ score of approximately 70 or below is commonly used as a threshold for identifying intellectual disability.</div>
</li>
</ul>
</li>
</ol>
<p align="justify"><b>Adaptive Behavior:</b></p>
<ol>
<li style="list-style-type: none;">
<ul>
