Both may involve repetitive actions, strong feelings of anxiety, and behaviours that seem ritualistic. This can lead to confusion between the two, or critically, diagnostic overshadowing can occur. This is where one condition masks or hides the other, making it harder to identify both. For example, PDA-related behaviours can be mistaken for OCD, or OCD symptoms might be missed because they are wrongly attributed to autism or PDA. Understanding the differences is key to providing the right support.<\/p>\n<p>[\/et_pb_text][\/et_pb_column][\/et_pb_row][\/et_pb_section][et_pb_section fb_built=&#8221;1&#8243; _builder_version=&#8221;4.27.4&#8243; _module_preset=&#8221;default&#8221; background_color=&#8221;gcid-d4d84b5e-d061-48e7-894c-a52b4e3d47de&#8221; custom_padding=&#8221;||||false|false&#8221; locked=&#8221;off&#8221; global_colors_info=&#8221;{%22gcid-d4d84b5e-d061-48e7-894c-a52b4e3d47de%22:%91%22background_color%22%93}&#8221;][et_pb_row _builder_version=&#8221;4.27.4&#8243; _module_preset=&#8221;default&#8221; custom_padding_phone=&#8221;||24px||false|false&#8221; locked=&#8221;off&#8221; global_colors_info=&#8221;{}&#8221;][et_pb_column type=&#8221;4_4&#8243; _builder_version=&#8221;4.27.4&#8243; _module_preset=&#8221;default&#8221; global_colors_info=&#8221;{}&#8221;][et_pb_heading title=&#8221;What is OCD?&#8221; _builder_version=&#8221;4.27.4&#8243; _module_preset=&#8221;default&#8221; title_level=&#8221;h2&#8243; title_text_align=&#8221;left&#8221; custom_margin=&#8221;0px|0px|0px|0px|false|false&#8221; custom_padding=&#8221;0px|0px|16px|0px|false|false&#8221; title_text_align_tablet=&#8221;left&#8221; title_text_align_phone=&#8221;left&#8221; title_text_align_last_edited=&#8221;on|desktop&#8221; global_colors_info=&#8221;{}&#8221;][\/et_pb_heading][et_pb_text _builder_version=&#8221;4.27.4&#8243; _module_preset=&#8221;default&#8221; custom_margin=&#8221;0px|0px|0px|0px|false|false&#8221; custom_padding=&#8221;0px|0px|16px|0px|false|false&#8221; custom_padding_tablet=&#8221;32px|0px||0px|false|false&#8221; custom_padding_phone=&#8221;0px||16px||false|false&#8221; custom_padding_last_edited=&#8221;on|phone&#8221; text_orientation_tablet=&#8221;&#8221; text_orientation_phone=&#8221;left&#8221; text_orientation_last_edited=&#8221;on|phone&#8221; global_colors_info=&#8221;{}&#8221;]<\/p>\n<p>OCD stands for Obsessive Compulsive Disorder.

Both may involve repetitive actions, strong feelings of anxiety, and behaviours that seem ritualistic. This can lead to confusion between the two, or critically, diagnostic overshadowing can occur. This is where one condition masks or hides the other, making it harder to identify both. For example, PDA-related behaviours can be mistaken for OCD, or OCD symptoms might be missed because they are wrongly attributed to autism or PDA. Understanding the differences is key to providing the right support.OCD stands for Obsessive Compulsive Disorder. Breaking down the words helps us understand what this means: Obsessive \u2013 when a thought, image, or feeling becomes overwhelming and takes over someone\u2019s mind. Compulsive \u2013 the action the person feels they must do to reduce the distress caused by the obsession. This cycle of obsessive thoughts and compulsive actions can be intense and difficult to break. Even though people with OCD often know their thoughts don\u2019t make sense, they feel very real and hard to ignore.Obsessions in OCD are usually unwanted and distressing thoughts, images, or urges. They come into a person\u2019s mind unexpectedly, causing anxiety or fear.
